GOODYEAR, Ariz. — The buzz was palpable as Jurrangelo Cijntje strode in from the bullpen, his custom two-way glove snug on his right hand. The crowd, braving the chilly Arizona night, leaned in with anticipation. Would the Mariners’ first-round draft pick pitch left-handed? Right-handed? Or would he switch it up mid-outing, keeping everyone on their toes?
The answer, as it turned out, was a little bit of everything—and it was electric.
Cijntje, baseball’s newest switch-pitching sensation, delivered a performance that was equal parts spectacle and substance during the MLB Spring Breakout game Friday night. While the Guardians’ prospects edged out the Mariners’ young stars 8-7, the score felt almost irrelevant. The real story was Cijntje, whose rare talent had fans, scouts, and even the MLB gameday tracker guessing. (For the record, the tracker listed his pitching hand as “undefined.”)
The Switch-Pitcher Show
Cijntje’s two-inning outing was a masterclass in versatility. He threw 40 pitches, 24 for strikes, and touched an eye-popping 99 mph with his fastball. He struck out two, walked two, and gave up two hits—though his final line could’ve been even cleaner if not for an error on a potential double-play ball.
But the real magic came in the details. Cijntje threw just *one* pitch left-handed—a groundout to Travis Bazzana, the Guardians’ top prospect and last year’s No. 1 overall draft pick. From there, he stuck to right-handed pitching, even against a lineup stacked with left-handed hitters. His final pitch of the night? A 97-mph fastball that left Bazzana swinging at air for a strikeout.
“That was a lot of adrenaline,” Cijntje said afterward. “Especially sort of getting your foot in and getting a taste of it.”
The Mariners’ Master Plan
While Cijntje’s ability to pitch from both sides is undeniably cool, the Mariners have a clear plan for his development. For now, they see his future as a right-handed starter, with the occasional left-handed pitch mixed in for strategic matchups. It’s a delicate balance, and one that requires careful management of his workload and mechanics.
“It’ll be a learning experience for us all,” said Mariners general manager Justin Hollander. “For our coaches, for our high-performance department, and Jurrangelo doing it on a pro schedule throughout a five-, six-month season.”
This season, Cijntje will primarily pitch right-handed in his weekly starts, with the option to throw lefty to a few hitters if the situation calls for it. His midweek side sessions will focus on right-handed mechanics, with some left-handed work sprinkled in during games. It’s an unconventional approach, but for a player as unique as Cijntje, conventional just doesn’t cut it.
The Rest of the Prospects
While Cijntje stole the show, the game was also a chance for other Mariners prospects to shine.
– Tai Peete, the Mariners’ No. 12 prospect, was the hitting star of the night, going 3-for-3 with a two-run homer in a lefty-on-lefty matchup. Peete, who’s transitioning from shortstop to center field this season, showed off his athleticism and power. “I feel like I can cover some ground,” Peete said. “Just being able to run and show off my athleticism is what I’m doing.”
– Jared Sundstrom, ranked 24th in the system, also made noise with a two-run homer off a hanging slider from Guardians righty Austin Peterson.
– On the defensive side, Cole Young turned heads with a slick backhanded play at second base to end an inning, reminding everyone why he’s one of the organization’s top infield prospects.
Why This Matters
Switch-pitchers are a rarity in baseball, with only a handful of players in MLB history successfully pulling it off. Cijntje’s ability to throw from both sides isn’t just a novelty—it’s a potential game-changer. By keeping hitters guessing, he could neutralize platoon advantages and give the Mariners a unique weapon on the mound.
But his journey is about more than just his arm(s). It’s about innovation, adaptability, and the relentless pursuit of greatness. As Hollander put it, there’s no blueprint for developing a switch-pitcher. Cijntje and the Mariners are writing the playbook as they go, and that’s what makes his story so captivating.
What’s Next for Cijntje?
The road to the majors is long, but Cijntje’s Spring Breakout performance was a promising first step. As he continues to develop, fans can expect more moments of brilliance—and maybe even a few more left-handed pitches to keep things interesting.
For now, though, Cijntje is focused on the basics: honing his craft, staying healthy, and embracing the challenge of being a trailblazer. “I’m just trying to get better every day,” he said. “This is just the beginning.”
The Bigger Picture
Cijntje’s debut wasn’t just a win for the Mariners—it was a win for baseball. In a sport that thrives on tradition, his unique talent is a reminder that innovation still has a place on the diamond. Whether he’s throwing 99 mph from the right side or keeping hitters off-balance from the left, Cijntje is proof that the future of pitching is anything but predictable.
So, as the Mariners’ prospects pack up and head to their respective minor league assignments, one thing is clear: Jurrangelo Cijntje is a name you’ll want to remember. Because if his Spring Breakout performance is any indication, this is just the start of something special.
And who knows? Maybe one day, switch-pitchers will be the norm, not the exception. If that happens, we’ll have Cijntje—and his custom two-way glove—to thank. ⚾
