Slow fastballs, tech wizardry and the perfect name: Meet the newest Jewish major leaguer

Jake Fishman’s heater may not touch 90, but it was effective in his MLB debut

Until recently, Jake Fishman was known more as an IT whiz than for his unorthodox fastball.

“I’ve always been a person that people come to for technology problems,” Jake Fishman told a local news channel in May. At the time, Fishman was pitching for the Miami Marlins’ Triple-A affiliate, and his IT-focused YouTube channel, “Fish Tech,” was supplementing his income.

But in Fishman’s major league debut Sunday, he was the one creating technical difficulty — with a fastball so slow MLB’s pitch-tracking system thought it was a changeup.

Whatever you want to call his 87-mph two-seamer — Fishman calls it a sinker — it seemed to work.

With family and friends in attendance, Fishman, who is Jewish and pitched for Team Israel at last year’s Olympics, spun the sinker and his curveball into 10 outs Sunday against the New York Mets, allowing one run. It’s about as good an outing as a long reliever could ask for, much less for a major league debut.

“Honestly I thought it went really well,” Fishman said Monday in an interview. “I was really happy with how many strikes I threw and attacked the guys.”

The Marlins’ social media team was quick to capitalize on their newest player’s perfect name:

His call-up was a short one, however, as the Marlins designated Fishman for assignment on Monday — which gives other teams the opportunity to claim him off waivers before he can be demoted to the minors — to make room on the roster for a player returning from injury.

Road to The Show

Fishman grew up in Sharon, Massachusetts, where he attended Temple Klal Yisrael’s Hebrew school. He was also bar mitzvahed at the synagogue.

After he was passed over for athletic scholarships coming out of Sharon High School, he enrolled at Division III Union College, in Schenectady, New York. All Fishman did there was lead college baseball with a 0.41 earned-run average — and take a few computer science courses that would come in handy later. When the Toronto Blue Jays picked him in the 30th round of the 2016 draft, he became the first player drafted in the school’s history.

Six years later, Fishman is one of only a handful of Division III alumni in the bigs.

“It just feels amazing, to be honest,” Fishman said about the callup. “You spend so much time in the minor leagues, and it all builds to this moment.”

Fishman took the mound with two on and two out in the third inning — the Marlins’ starting pitcher had already given up six runs — where he faced Mets all-star shortstop Francisco Lindor.

“Your first major league batter you’re not really expecting Francisco Lindor is going to be at the plate with the guy on first and second,” he said, adding that he was “a bit shaky” when he first looked into the batter’s box. “Then when I threw that first pitch for a strike, I was like, ‘All right, I think we’re gonna be okay.’” 

His third pitch, clocked at 87 mph, was originally registered as a changeup by Statcast, MLB’s pitch-tracking technology.

But Statcast was confused — that’s actually about the average speed of Fishman’s heater, which topped out yesterday at a leisurely 89.1 mph. For comparison, the average speed of an MLB fastball in 2021 was 93.5.

How does the 6’3” lefty get batters out? Fishman relies on deception, turning his back to home plate during his delivery and hiding the ball until the last second, when he wheels and throws it sidearm.

According to Fishman, the Marlins don’t value fastball velocity as much as release height and downward movement — where his sinker excels.

“For probably half of my career, velocity was a huge concern for me,” he said, “until the analytics started coming out and saying that ‘Wait, these guys have really great fastballs.’ Even though it might not be 100, it’s got the movement profile to be effective.”

Fishman was called up to a Marlins team that is 17.5 games out of first place, and he is unlikely to be moved to a contender before Tuesday’s trade deadline — though another Jewish reliever, Scott Effross, was acquired Monday by the Yankees.

But the quality of his debut is a good sign for Team Israel, which has strong hitting depth but is shallow in the bullpen. And despite his rookie status in the majors, Fishman will bring something that some players on the World Baseball Classic team may lack — tournament experience. 

As for his tech wizardry, the rigors of his major league assignment may put any new tool tips on hold. In the meantime, you can download his most successful creation — an audio visualizer for the Macbook Pro touchbar — for just $4.99.
