Seattle Mariners switch-pitching prospect stars in pro debut
Jurrangelo Cijntje’s pro debut certainly lived up to the hype.
Another M’s prospect moves into Baseball America’s Top 100
Cijntje, the Seattle Mariners’ 2024 first-round draft pick and unicorn switch-pitching prospect, struck out six batters over four scoreless innings in High-A Everett’s 8-0 win over Spokane on Saturday night. He allowed just one hit and two walks.
And yes, he threw with both arms.
Making his minor league debut, Cijntje pitched right-handed for 11 batters and left-handed for three baters. As a righty, he struck out six batters and retired 10 of 11. As a lefty, he retired one batter and yielded two walks.
Cijntje told the Spokesman-Review that his right-handed fastball hit 100 mph on the radar gun Saturday night. Last month, he reached 98.9 mph from the right side during the Mariners’ Spring Breakout game for top prospects.
Cijntje (pronounced SAIN-jah) was the No. 15 overall pick in last summer’s MLB Draft. The 21-year-old Dutch native spent his college career at Mississippi State, where he typically threw right-handed against righty batters and left-handed against lefty batters.
During the Seattle Sports radio broadcast of last month’s Spring Breakout game, Mariners general manager Justin Hollander explained how Cijntje’s pitching profile differs by arm.
“It is very different – more of a low release, more Luis Castillo four-seamers, sliders, developing changeup right-handed,” Hollander said. “And left-handed, it’s more sinker/slider. Taylor Saucedo is a fair comp. Way different mix. I do think that will evolve over time as he gets in our system.”
What’s next for M’s switch-pitching prospect Jurrangelo Cijntje
While Cijntje’s stuff is currently better from the right side, Hollander said the plan is for him to continue developing both arms.
Switch-pitchers have been an extreme rarity in MLB history. The only one who did so consistently was journeyman reliever Pat Venditte, who made 61 relief appearances in the majors between 2015 and 2020.
Cijntje throws significantly harder than Venditte, who as a 45th-round pick was not nearly as highly regarded of a prospect.

Thanks to Carrie Brown for the westward view of our Saturday night sunset. The high today hit 68 at the airport – eight degrees above normal – but nowhere near the record for this date, which was 89 degrees back in 2016. The forecast suggests two more days of partly sunny, almost-70-degree weather, before the chance of rain returns.
CHICAGO (AP) — The struggling New York Mets placed former Seattle Mariners second baseman/designated hitter Jorge Polanco on the 10-day injured list on Saturday with a right wrist contusion.
Mariners Injury Update: Latest on Robles, Vargas and more
The move was made retroactive to Wednesday, a day after Polanco went 0 for 4 with two strikeouts in a 2-1 loss at the Los Angeles Dodgers. The 32-year-old Polanco is batting .179 (10 for 56) with a homer and two RBIs in his first season with New York, which has lost nine straight.
“When doctors first took a look at him, it looked like he got hit by a pitch when he didn’t,” manager Carlos Mendoza said. “In talking to him, it was just a couple of swings that he took that night. … He didn’t think much of it, but just got worse the following day.
“So you just got to let it calm down a little bit and then we’ll go from there. But we don’t have a timetable for how long this is going to last.”
Polanco, who signed a two-year, $40 million contract with the Mets in December, also has been dealing with an ankle issue.
“He was trending in the right direction,” Mendoza said of the ankle injury. “It’s definitely going to help, obviously now with him being shut down. But the biggest thing now is that we’ve got to take care of that wrist.”
Polanco spent the previous two seasons with the Mariners, who acquired him in a February 2024 trade with the Minnesota Twins.
Polanco struggled during his first season with Seattle in 2024, hitting just .213 with 16 homers in 118 games while playing through a knee injury that didn’t become public knowledge until after the season.
But after the Mariners somewhat surprisingly brought him back for a one-year contract in 2025, Polanco rebounded to hit .265 with 26 homers and an .821 OPS in 138 games last season. He then added three homers during Seattle’s playoff run, along with a 15th-inning walkoff single in Game 5 of the American League Division Series that sent the Mariners to their first ALCS in 24 years.

SEATTLE – Brandon Nimmo hit a leadoff home run, Jacob deGrom threw four shutout innings and Gavin Collyer earned his first career win as the Texas Rangers beat the Seattle Mariners 5-0 on Friday night.
Seattle lost its fourth straight game, and was shut out for the fourth time in 21 games, falling to 8-13. The Mariners were shut out six times during the 2025 season. Texas won its third straight game.
Nimmo led off the game with a 372-foot shot to right field off Mariners starter Logan Gilbert (1-3). It was Nimmo’s 16th career leadoff homer and second of the season. He also hit a leadoff home run on April 11 in a 6-3 loss to the Los Angeles Dodgers.
DeGrom effectively maneuvered through Seattle’s lineup, and worked out of a one out, bases-loaded jam in the first inning. The two-time Cy Young Award winner recorded two of his three strikeouts after walking Josh Naylor to load the bases. Randy Arozarena fanned on a curveball, and Luke Raley swung through a fastball.
Texas added to its lead after Nimmo’s homer. Wyatt Langford’s single to left scored Corey Seager, who led off the third inning with a double. The Rangers stretched the lead to 3-0 on an RBI single from Jake Burger in the seventh.
The Mariners’ best scoring chance came in the sixth after Collyer (1-0), who worked 1 1/3 scoreless innings, left the game.
J.P. Crawford singled to left off Tyler Alexander with two out, and Mariners third base coach Carlos Cardoza sent Naylor from second base, but he was thrown out by Langford.
Texas added two more runs in the ninth on a sacrifice fly by Andrew McCutchen and an RBI double by Josh Jung.
Seattle third baseman Brendan Donovan left the game early due to a left hip issue.
Mariners right-hander Bryce Miller, who started the year on the injured list with a left oblique injury, was at T-Mobile Park for the first time this season. He will begin a rehab assignment with Triple-A Tacoma on Saturday.
Up next
Mariners RHP George Kirby (2-2, 3.25) will face Rangers righty Nathan Eovaldi (2-2, 5.40) on Saturday afternoon.
