What to Expect from Mariners Shortstop Cole Young

The Mariners made it official on May 31, as Cole Young is headed to Seattle. Young got the call after a hot stretch in Tacoma, as he was statistically one of the best hitters in the Pacific Coast League. Now, he joins a Mariners team looking to stay in the AL playoff race.

A Look at Young

Two years ago, the Mariners grabbed Colt Emerson, a big-time high school shortstop from Ohio, with the 22nd pick. One year earlier, Seattle went to Pennsylvania to grab Cole Young, a Pittsburgh-born kid, with the 21st overall pick in the 2022 MLB Draft.

Since then, Young’s steadily moved up the Mariners’ organization. Young posted a .847 OPS over 126 games during his first full season in 2023, between Low-A and High-A. The now-21-year-old did very well in Arkansas (AA), as he slashed .271/.369/.390 (.759 OPS) with 23 stolen bases and played a key role for the Travelers’ Texas League championship team.

He spent all of 2025 to this point with Tacoma (AAA).

Young struggled out of the gate this season but caught fire this past month. The 21-year-old batted .366/.467/.673 (1.140 OPS) over 26 games with the Rainiers, with five home runs and 18 extra-base hits over 26 games. He led the PCL in hits (37) during May, one ahead of teammate Harry Ford.

The draw on Young is his eye, which I’ll get into in a second. However, it’s worth noting that the former first-round pick can hit for power. He’s got quick hands, showed the ability to catch the ball out in front, and posted a respectable 6.1 Barrel:PA this season in Tacoma. Between 2023-24, Young hit a combined 20 home runs.

Not to mention, Young showed great feel for his hit tool. He doesn’t miss much (17.9% Whiff%), and even when he was a little behind, Young still did damage by taking it the other way.

Getting back to his eye, Young’s ability to get on base has arguably been his calling card. The 21-year-old posted a .423 OBP in his first taste of pro ball in 2022 and hasn’t slowed. Young has a career OBP of .388 in the Minors and with Tacoma, wasn’t a habitual chaser (23.3%).

Defensively, Young’s split time between second and short this season. Given the speed, one would expect good range from the 21-year-old, and he’s been very successful holding down second. Between 125 games at second between 2023-25, Young only made two errors at the position.

The Mariners officially selected Cole Young’s contract on May 31. Seattle DFA’d Will Klein and optioned Leo Rivas in corresponding moves.

Analysis

The Mariners have tried a lot of different options over the years to fill out the second base position. Sam Haggerty, Josh Rojas, Jorge Polanco — who’s seen most of his time as a DH this season — and utilityman Dylan Moore are among those names.

Moore’s been very productive, with eight home runs and eight stolen bases, along with a .803 OPS that would be a career-best if that held. However, the 32-year-old can play multiple positions.

Young profiles as a future leadoff man with his ability to get on base but that likely won’t be in the cards yet with J.P. Crawford, who has a .377 OBP this season. But what Young can do is help fill out a lineup that needs some depth & punch.

Ben Williamson is a valuable utilityman thanks to his speed and defensive ability but hasn’t been productive at the plate, with only five extra-base hits in 38 games. Donovan Solano (.413 OPS) and Miles Mastrobuoni (.590 OPS) are other players who’ve been below-average offensively.
