Luke Stevenson, a young catcher in the Mariners' minor league system, is off to an impressive start with the Everett AquaSox this season. After a strong debut in 2025, Stevenson is hitting .400 with a 1.169 OPS through his first six games, flashing the plate discipline and left-handed power that have the organization excited about his future.

Why it matters

Stevenson's early-season performance is generating promotion buzz, though the Mariners are likely to take a patient approach with his development given they already have one of the best catchers in baseball, Cal Raleigh, at the major league level. Stevenson's ability to control the strike zone and impact the game with both his bat and his work with the pitching staff make him an intriguing prospect worth monitoring.

The details

In 22 games with Modesto in 2025, Stevenson hit .280 with a .460 on-base percentage and an .860 OPS, showcasing an advanced approach at the plate. He's carried that over to Everett this season, hitting .400 with a 1.169 OPS, 8 hits, 5 RBIs, 1 home run, and 6 walks against 8 strikeouts through his first 6 games.

  • Stevenson made his professional debut with Modesto in 2025.
  • Stevenson is currently playing for the Everett AquaSox in 2026.
