Born on May 23, 2002, he grew up dreaming of the big leagues, swinging a bat with determination and grit. Teams noticed his potential early, and the Seattle Mariners signed him as an international free agent in 2018. That moment kicked off a journey filled with hard work, standout performances, and a rapid rise through the minors.

Add in his growing power at the plate, and you’ve got a player who blends old-school hustle with modern flair. By 2024, he’d already debuted in the majors, but 2025 marks his chance to shine brighter than ever.
From the Dominican Republic to the Big Leagues
Jonatan Clase hails from Santo Domingo, Dominican Republic, a hotbed for baseball talent. Born on May 23, 2002, he grew up swinging a bat and chasing dreams on dusty fields. Scouts noticed his raw talent early, and the Seattle Mariners signed him as an international free agent in 2018. At just 16, Clase showed flashes of brilliance with his speed and switch-hitting ability. His journey wasn’t overnight, though—he spent years grinding through the minors, honing his craft step by step.
Clase’s minor league career kicked off with promise. He quickly earned a reputation for his legs, stealing bases like a thief in the night. In 2023, he swiped an eye-popping 79 bases across the minors, proving he could outrun just about anyone. Meanwhile, his bat started catching up, smashing 20 home runs that same year. Fans and analysts alike began whispering his name, wondering when he’d get his shot at the majors.
The Big Leap: MLB Debut and Early Struggles
Clase’s dream came true in 2024 when the Seattle Mariners called him up. He debuted on April 15, stepping onto the field with nerves and excitement pumping through his veins. That rookie season, he played 19 games for Seattle, hitting .195 with a double, three RBIs, and three stolen bases. Sure, the numbers didn’t scream superstar, but they showed grit. Clase faced big-league pitching for the first time, and like many rookies, he stumbled. He struck out often, posting a 34% strikeout rate in those early games.
Despite the rocky start, Clase’s speed dazzled. Clocking a sprint speed of 30.0 feet per second—one of the fastest in the league—he turned heads every time he hit the basepaths. Coaches saw potential, but they also knew he needed time. Seattle traded him to the Toronto Blue Jays on July 26, 2024, in a deal sending reliever Yimi García the other way. For Clase, it marked a fresh start, a chance to prove himself with a new team hungry for young talent.
A New Home in Toronto: Breakthrough Moments
Toronto welcomed Clase with open arms, and he didn’t waste time making an impact. After some seasoning in Triple-A Buffalo, the Blue Jays called him up again in September 2024. This time, he looked sharper, more confident. In six games with Toronto, he hit .375, including his first MLB home run on September 25 against the Boston Red Sox. That blast—a solo shot—helped the Jays snap a five-game losing streak and knocked Boston out of playoff contention.
Clase celebrated the milestone with a heartfelt “Gloria a Dios” (Glory to God) on social media, showing his gratitude and faith. Fans roared as he rounded the bases, sensing they’d just witnessed the start of something special. He also flashed his glove, making a diving catch in center field against the Tampa Bay Rays on September 23. Suddenly, Clase wasn’t just a speedster—he was a playmaker.
Spring Training 2025: Hamstring Hurdles and Hot Starts
Fast forward to March 2025, and Clase’s stock keeps rising. Spring training with the Blue Jays brought both challenges and triumphs. Early on, a sore hamstring slowed him down, keeping him out of Grapefruit League action. Manager John Schneider stayed optimistic, noting Clase’s progress with running drills. By March 1, Clase returned to the lineup against the Atlanta Braves, proving his legs still had that lightning.
Analysts now peg him as a contender for Toronto’s Opening Day roster. With outfielder Daulton Varsho sidelined by shoulder surgery, Clase could snag a spot in the outfield. His switch-hitting versatility adds depth, and his speed gives the Jays a weapon on the bases. While his role might start small—think fourth outfielder—his upside looms large. If he sharpens his plate discipline, the sky’s the limit.
What Makes Jonatan Clase Special?
So, what sets Clase apart in a league brimming with talent? First, his speed jumps off the charts. That 30.0 ft/sec sprint speed isn’t just a stat—it’s a game-changer. He stretches singles into doubles, swipes bags with ease, and pressures defenses every time he’s on base. In an era where power often dominates, Clase brings a throwback vibe, reminiscent of speedsters like Otis Nixon or Rickey Henderson.
Next, his switch-hitting ability doubles his value. He swings from both sides of the plate, adapting to lefties and righties alike. In the minors, he posted solid numbers—think .263/.344/.439 in 2024 across Triple-A Tacoma and Buffalo. Add in 12 homers and 38 steals in 94 games, and you’ve got a player who blends power, patience, and pace. Sure, his 27% strikeout rate needs work, but he balances it with a 13% walk rate, showing he’s no free-swinger.
Defensively, Clase holds his own in the outfield. He covers ground like a cheetah, tracking fly balls with instinct and flair. That diving catch in September wasn’t a fluke—it’s who he is. Put it all together, and you’ve got a five-tool prospect with room to grow.
