The $100 Baseball Bat That Could Save The Major Leagues Millions

This ergonomic bat has MLB approval and could save millions a year in player injuries. So why won’t anyone manufacture it?

It’s April 9, 2013. Gordon Beckham of the White Sox stands at the plate facing down the Nationals pitcher Gio Gonzalez. The promising young hitter has weathered a tough few years of disappointing averages, but his 2013 season is off to a solid start. He’s batting over .300, meaning it could be the season of the turnaround, the year that redirects his career to come.

A 2-2 fastball fires from the mound. Beckham swings big, spinning almost 360 degrees before hunching over in pain. No one knows why. Moments later, Beckham would be in the dugout with trainers staring at his hand with a strange, clinical detachment, curious how his body had betrayed him.

In reality, the pain had little to do with his mega swing. Beckham actually sustained an injury on the pitch before—a typical high outside fastball that he appeared to innocuously foul.

"When I swung through the ball, I definitely felt it," he tells me later. "It did not feel good."

Beckham, who’d never broken a bone in his life, fractured his hamate—a bone in the wrist all too familiar to major league players for its propensity to crack unexpectedly. He’d require surgery and couldn’t be back to play for seven weeks. His turnaround was stopped in its tracks.

It Could Have Been Prevented

At the same time, a graphic designer named Grady Phelan was formatting a Kickstarter campaign for an invention that had consumed the last decade of his life, along with $125,000 in personal savings. Called the ProXR, his patented creation tilted the knob of a bat by 23 degrees specifically to prevent the fairly common hamate fracture that Beckham had incurred.

The especially bitter irony? Not only did Phelan already have a small pile of supporting research along with the MLB’s approval to use his bat in play; the ProXR had been admitted into the Hall of Fame three years earlier! Despite such an endorsement, Phelan couldn’t convince a major bat manufacturer to produce the ProXR. And without the major bat manufacturers on board, it was impossible to convince players to adopt the technology.

Phelan’s Kickstarter campaign failed to reach its $40,000 goal while Beckham sat on the disabled list for seven weeks. Almost $800,000 in salary effectively disappeared to a benched Beckham, and the White Sox slipped to second-to-last place.

But as I would learn in researching this very article, that wasn’t the end of the story for Grady Phelan, the ProXR, or even Gordon Beckham (who’d return from his injury batting over .300). Just when things seemed the most hopeless for the homegrown ergonomic bat, the largest, most historical brand in baseball took serious notice.

A Game Of Traditions

Even though Ray Chapmen died after being struck in the head by a pitch in 1920, it took almost 40 years and a grandfathered MLB mandate for many reluctant players to adopt batting helmets. Today, it would be ridiculous to consider the helmet as contrary to the sport’s purity, but even the most insignificant tropes of baseball have a long half life.

No doubt, the same sense of tradition that fought the helmet for so many years has kept the baseball bat relatively stagnant throughout history. The construction has become absurdly precise, the wood has gotten harder, and bat manufacturers have amassed a very scientific understanding of moisture content and grain, but the bat design itself has gone nowhere. Before the ProXR, the MLB hadn’t approved a single new bat design since the 1970s. And maybe that wouldn’t matter, if not for one important catch:

"Bats haven’t changed in 135 years, but bat grip has changed," Phelan explains. You see, baseball used to be a game of finesse. Look up photos from 1900 and earlier, and you’ll spot players choking up to bunt and slap at the ball. It was a calculated approach to batting, built to find the holes in a team’s defense.

Around 1910, players adopted a new grip, dropping their hands to the bottom of the bat in a quest for most swing speed, beginning a trend that would only accelerate as strategy gave way to brute-force homerun hitting. So the bat’s knob—once a safety catch—began grinding its way into the bones of every major league player as they rode the bottom of the stick for maximum speed.

Today, when a baseball player rolls their wrists through the point of impact with the ball, pressure skyrockets, and their hamate endures forces as great as 80 PSI—meaning that bone is ostensibly hit by a hammer. In response, the ProXR isn’t just lathed symmetrically like most bats. Instead, it tilts that knob by 23 degrees (which happens to be the precise range of motion of the human wrist) to work with human anatomy to mitigate hamate impacts by roughly 25%. In theory, that’s enough to prevent many breaks.

Needing Advocates

The logic behind the ProXR isn’t really all that difficult to grasp. In fact, while it was convincing enough to be tested (successfully) at the Washington University School of Medicine’s Biometrics Lab, getting a professional MLB player to try it out is a whole other challenge. It’s hard to imagine why that may be. After all, Tiger Woods adopts the newest club technology Nike has to offer year after year. What makes baseball players different? It comes back to that idea of tradition.

"I think ball players are superstitious," Mike Hessman tells me. "If they have something they like, it’s hard to break them of that."

Hessman is a journeyman ball player currently at the Louisville Bats. He holds the all-time homerun record for minor league play (with over 400 homers as of this season). Hessman’s other claim to fame is that he has a bat in the Hall of Fame—specifically, a ProXR he borrowed from a buddy during batting practice and eventually tried out in a major league start just because "it felt good." Hessman ended up hitting a double at Wrigley Field, which was the bat’s first hit in the majors. A few days later, the Hall of Fame claimed the prototype for itself (recognizing the ProXR’s inauguration as either history or novelty), and Hessman’s interest faded a bit as he made his way to play ball in Japan. (The Milwaukee Brewers’ Prince Fielder used it later in a few games as well.)

I ask Hessman if it would be hard for a professional to adjust their swing to the ProXR’s unconventional design. He estimates that a day of batting practice should be adequate. The tougher challenge is, again, one of changing a player’s mentality.

"I think minor leaguers will try anything. They see something new and want to check it out," Hessman explains. "[But] I think the guys that are established don’t like to change a lot of things that have worked for them in the past."

It’s a sentiment that seems mostly true. Though in fact, Louisville Slugger makes somewhere around 400 different permutations of their iconic bats to appease particular player tastes, and one recent bat startup has claimed roughly 20% of the MLB bat market specifically by selling the idea of extremely subtle, artisan customization.

Phelan explains the shortage of early adopters in the majors through a slightly more nuanced lens. Players are surely bat-loyal, he learned attending the Cardinals spring training camp in 2006, but they’re brand loyal, too. "Very few guys will change their bat brand. If you’re a Louisville Slugger guy, you’re going to die a Louisville Slugger guy," he says. "At camp, it became apparent to me that these guys like my tech, but they love their brand of bat."

"So I asked them, ‘If you can get this on your brand of bat, would you use it?’ Their answer was ‘I’d give it a try."

Wooing The Big Boys

Grady Phelan is a true basement inventor. He hasn’t played organized baseball since high school. He was inspired to create the ProXR, not while having beers with some deep network of major league buddies, but while swinging at hickory nuts in his backyard alongside his kids. The bat slipped from his hands, almost struck his son, and left a strange bruise on Phelan’s hand. After months of research, Phelan would learn that his grip’s compression had short circuited his own nerves—another nasty side effect of choking down on the traditional knobbed baseball bat—and he’d eventually create his patented design by dumping six figures into ideas dreamed up in his home woodshop.

Hickory nuts make for a great design anecdote but a very humble industry pitch. When Phelan received a patent confirmation for his ProXR design in 2006, he immediately brought the idea to a big company in his own hometown of St Louis: Rawlings.

"I don’t want to put Rawlings on the spot," he insists, "but I basically got this response:"

a. Nobody is going to use that.
b. You can’t ever manufacture that.
c. You’ll never get MLB to approve that.
d. You’ll never get that in a game.
e. You’ll never get a player to play it.

It was a damning rejection (and Rawlings was not available for comment), but Phelan interpreted the negativity as a "to-do list" instead of a dead end. As of 2010, a, b, c, d, and e had all been checked off the list—a huge accomplishment by any metric—but Rawlings still hasn’t expressed interest in licensing the design.

The ProXR—before finishing the tilted knob.

From Phelan’s perspective, he not only needs a company like Rawlings to sell players on trying the bat for safety reasons; he needs Rawlings to sell players on trying to bat for performance reasons. Because the ProXR has a tilted knob, it could theoretically offer players a bit more finesse during the final milliseconds before striking the ball. Maybe that’s true. Maybe it isn’t. But the only way for anyone to know is for the bat to get into the hands of more players. And the best way for that to happen is for a major bat maker to push the tech.

"This will sound cheesy, but this is a David and Goliath thing, and a ‘it’s not invented here’ thing. I’m a graphic designer and an inventor who’s trying to convince bat companies that this is the real deal, that there are serious problems with the bat. And it’s not in their best interest to admit there are problems with the bat."

As For Beckham…

The pro companies won’t touch it, so the baseball players won’t touch it. But what about those who’ve sustained hamate injuries? What about Gordon Beckham himself? Does he wish he’d been using a ProXR to avoid the hamate injury?

"If you’d asked me two months ago, I might have said, ‘Yeah, I wish I’d been using it," Beckham admits. "Now that I’m back swinging the bat okay, I’d say no."

Like most major leaguers, Beckham is brand-biased, having used the same bat (an Old Hickory) since coming up to the majors in 2008. But when I asked if he’d heard of this safer bat, he divulged that he had actually swung a ProXR before. Beckham, ever the southern gent, called it a "great concept" that "definitely felt better" in regards to its tilted knob. He even went on to tell me that "it felt like you could really pull that bat through the zone really nice"—meaning there really may be something to Phelan’s arguments about more wrist flexibility being a good thing for striking the ball.

His qualm, however, was a big one: Because the bat is asymmetrical, its margin of grip error is in some ways more like a golf club than a baseball bat. "If you grip the bat, you’ve gotta make sure you grip it exactly the right way," he explained. "If you’re not swinging and hitting the right perfect spot on the barrel, you’re going to have trouble."

That might not sound like a big deal—after all, golfers make it work—but players like Beckham will almost compulsively grip and regrip the bat, searching for that perfect feel of grain in their hands. It’s a habit that could be hard to break, which is why Beckham even suggests that the ProXR might work better for players when introduced to them young. Indeed, there’s little impetus for Beckham to switch now since the hamate is actually removed when broken, meaning it won’t be a recurring injury for him or any other baseball player.

"I feel like, for guys who have broken their hamate, they’re not going to use it," Beckham says. "For guys who’ve used a different bat for their whole life, it’s going to be difficult to change the feel of what they’re doing."

So Now What?

Despite Beckham’s grounding skepticism, I was left at a loss when parting with Phelan after a surprisingly fast hour on the phone. Sure, he was a humble basement inventor, but he seemed neither a shyster nor a quack. In fact, our discussion had proven that he had all the pragmatism of any good designer, and he had an incredible tome of knowledge on the topic to boot. If anything, the cruel joke was on him: His product was failing to catch specifically because of its watershed design.

Before hanging up, I’d asked if he’d pitched Hillerich & Bradsby, manufacturers of the Louisville Slugger (the official bat of the MLB). He had in September of last year.

Phelan assured me that the pitch had actually gone quite well, but how could that possibly be? He was still stuck honing his bats out of his basement. I wanted to know what could have gone wrong with Phelan’s sell—maybe baseball was having its own NFL crisis moment, and product manufacturers were afraid to touch injury. Maybe the bat companies were developing their own patented tech to mitigate hamate injuries without paying licensing. Or maybe Phelan had just completely misread the polite repartee of a disinterested company, and baseball at large was okay with the Gordon Beckhams of the world occasionally missing 6 to 8 weeks of play to injury.

"[We] were intrigued," Rick Redman, a Hillerich & Bradsby spokesperson tells me over email. "Our R&D team gets a lot of product pitches and they said that Grady’s presentation was one of the best they’d ever seen. But our focus has been on our MLB Prime which we introduced to MLB fields this season, a reinvention of our wood bat line with innovations that created the hardest wood bats we’ve ever made…"

It was a heck of a rejection—a total affirmation of Phelan’s work and a complete slap in the face of innovation at the same time. But the industry’s hesitance still made no sense. Why make harder bats in lieu of making them safer? Why say an idea was stellar but then ignore it?

Then, just a few minutes later, I received a surprising follow-up from Redman:

"A little addition, in a hallway conversation just a few minutes ago I learned from Bobby Hillerich, our Director of Wood Bat Operations, that he continues to work with Grady on this project and that we would like to have it in our repertoire for any players who want it. "

And with that, it sounds like after a decade of striking out, Grady Phelan may have finally landed a hit.

    Gary, its so simple theres no way it could be illegal, but i only have an idea nothing else, but after reading that other bat idea ithink my idea will solve many problems

  • harv413

    i have had this idea for a bat for the last 50 years that would revolutionize hitting with 1 small adjustment, anyone out there?

  • Grady Phelan

    Is it legal for use in play?
    Has it been done before?Do you have a patent?Do you have prototypes?Have you tested it with players?These would be the first five questions I would ask. If yes to all you may have something.

  • GTA_John

    I have read (and believe!) that the most difficult feat in all of sports is hitting a pitched baseball.  Consider this:  if you hit a baseball 2 times out of 10, you're unlikely to make it to the big leagues.  But if you hit it just one more time, 3 times out of 10, you'll go to the Hall of Fame.

  • Axe Bat

    I’m a representative from Baden Sports, and and one of the designers of the AXE bat. We applaud innovation and it’s great to see that others are recognizing that it’s time for bats to change. We have developed our own asymmetric handle which is currently being used by MLB All-Star Jimmy Rollins, and is being trained with by other MLB players. The AXE is also swung by over fifty colleges including 2012 Division III World Series Champion, Marietta College, and Division I schools University of Memphis and San Jose State.  The AXE shape is the result of years of R&D including a major university study that will be published soon. The oval, tapered shape of the AXE knob has been proven to provide better grip with less tension and our angled bottom and flat backside provide a freer swing and more powerful connection. By making the handle oval it is truly asymmetric (not merely round with an angled bottom as the ProXR), the hitter receives haptic feedback from the bat and can feel when they are out of plane.To clarify what Mark Wilson said above, the wrists are free to rotate because the oval axe knob transitions to a round handle where the top hand sits. The AXE bat actually has much greater range of motion than a traditional bat.

  • Batsirai Chada

    Great article - cool to see Fast Co helping the little guy with the big solution.

  • absurge

    chalbach is correct. you already need to hold a bat a certain way so the grain runs against the impact of the ball - all batters know that the label should be up or down..usually up, so this handle could in fact help solve for that :-)

    But i just think it's too late for pro batters to change. they have swung a bat over a million times, and now you are making it feel different, only to prevent a very rare injury without improving performance.... not convinced this will take off

  • Grady

    Injury protection is only a part of the benefits package of the ProXR technology. All indications are that by increasing the range of motion, ProXR does reduce compression forces but also gives batters specific performance benefits like greater plate coverage, more precise swings and better transfer of power from the hands to the ball.
    It is true that most current pro players are reluctant to try new technologies once they have made it to the "show". In my experience, it's the guys trying to break in who are more willing to try something new. 
    Basically, if a player believes they hit better, run faster or catch more effectively they will embrace what ever it is that they feel delivers those benefits for them. ProXR is still so new, that players are waiting to see if the first guy will step in and commit to it. Perhaps a player who is slumping, perhaps a player who tries it in the batting cages or even reads about it here. It will happen – have no doubt.

  • Jkjohnson1995

    The problem with this bat design especially with a wood bat is you have to hold it a certain way.  Which means you can't spin the bat in your hands. There is so much that has to go right in order to hit a 90mph baseball that the last thing you need to be thinking about is " are my hands in the exact right spot on the bat." 

    With the current bat design, the sweet spot on the bat goes all the way around the bat because the bat is symmetrical.  With the asymmetrical knob, you have to hold the bat the exact same way every swing and the sweet spot is on just one "spot" on the bat, not all the way around the bat.  Thus, either causing the bat to go "dead" a lot sooner or breaking even more than the traditional bats do today.

  • Bravesfan1018

     If it is suppose to be held a specific way usually it is contoured to naturally be held that way...

  • Chalbach

    I am not sure if have used a wooden bat before, but the first thing we were taught when moving to wooden bat summer leagues as kids was that you have to hold the bat with either the label facing directly towards you or directly away from you. You can't hit the ball on all sides of the bat due to the structure of the grain. Bats break very easily if you don't hit with the grain parallel to the swing plane. You shouldn't be rotating the bat to try to get it to wear evenly or something. That doesn't make sense.

  • beehut

    Did Mr. Phelan have anything to do with the AXE handle technology seen in Baden aluminum bats recently?  Very similar design.  But that would be the key, get the players using it while they're young...

  • Mark Wilson

    He did not. They're actually very different designs, too, with the exact opposite of goals. The oval-core axe bat seems meant to keep your wrists from rotating (like an axe!) while the round-core ProXR/traditional baseball bat is meant to allow them more range of motion. 

  • Greg Bailey

    While I certainly appreciate the diligence Mr. Phelan has given to solving the problem, I can't help wondering if there aren't simpler solutions.  Does the knob have to be asymmetrical?  Can't the end be softened symmetrically?  Softened radius bats already exist.  Furthermore, bat manufacturers create a sculpted rubber ring to soften the radius while simultaneously cushioning impacts created by compression.  It seems symmetry might garner greater acceptance.

  • Grady


    The symmetry of the knob is the essence of the problem with bats. Regardless of the slope or bell-shape of the knob, the relationship between the base-gripping hand and the knob changes when the hands roll over the knob when the knob is symmetrical. When properly angled, the knob fully engages the base hand providing even distribution of pressure and support.

    I believe players will accept the ProXR knob once they understand that it's not just about hamate protection but it's also a performance technology – quicker hands, great plate coverage, more precise swing and greater transfer of power from the hands to the ball. All that by making the knob angled to work with the range of motion of the hand.

    New thinking within old established organizations is very hard indeed. So many times new ideas are brought before the existing groups that will be most impacted and they will work hard at why not, or why not now - vs. we must, now more than ever. I call this the "white blood cells" within the existing organism come out to kill the new thinking. In many ways it is the preservation of the status quo - which is no surprise. Its like taking this new fangled idea "the automobile" in front of the buggy wip makers and all they can ask is "where's the horse, what no horse well this will never work..." This is a great write up and gives great insight into new product development and how grass roots thinking can be missed or over looked by those already in the seat of power and control holding back the improvements because they don't get it, or worse yet they do but they want a monopoly on innovation. Thanks for sharing... Batter Up!

  • rmintzes

    Great article.  However, according to other articles, and my brother (a freelancer at MLB network), Beckham sustained his injury on April 9, not March 12 (which would have been during the pre-season).

  • Mark Wilson

    You are absolutely correct! Fixing now. No clue how that wrong date got through.
