Luke Stevenson turned July into his own personal breakout tour, and the High-A Northwest League took notice. The Mariners catching prospect was named the league’s Player of the Month after a blistering stretch that pushed him to the top of the circuit’s offensive leaderboard.
The numbers tell the story in sharp relief. Stevenson’s monthly line climbed from .192/.366/.359 in May to .148/.365/.328 in June, then exploded to .338/.433/.753 in July. That jump in OPS from one month to the next was more than 500 points, a massive swing for a player who had been grinding through a rough patch earlier in the spring and early summer.
What makes the surge more interesting is that it didn’t come out of nowhere. Stevenson was producing at a similar level in the first month of the season, and as a 2025 first-round pick, there’s plenty of reason to think this version of him can stick.
He’s been more aggressive at the plate over the past few weeks, hunting damage earlier in counts and getting better pitches to drive. The whiff problems are still there, but his game doesn’t depend heavily on pure bat-to-ball ability when he’s unlocking that kind of raw power.
That power is the real carrying tool. From the left side, Stevenson brings light tower pop, and when you mix that with his excellent eye at the plate and strong work behind the dish, you get a profile that stands out. His leadership and catching skills only add to the appeal, and right now he looks like one of the most elite prospects in the system with a clear up arrow next to his name.
He’s kept it rolling into the early part of August, too, and will try to finish the minor league season on a high note.
Stevenson wasn’t the only Mariners farmhand putting up video game numbers in July. That distinction belonged to ACL outfielder Kelvin Alcantara, who posted a 1.266 OPS and a .400 batting average to earn the organization’s top hitter honors for the month.

Mariners Forced Into Another Pitching Shuffle Before 50th Anniversary Weekend
A pitching shuffle landed on the Mariners just as the club prepares for a milestone weekend at T-Mobile Park. Seattle announced a roster move that continues the churn on the mound, with the team getting ready for its first-ever Alumni Home Run Derby as part of its 50th Anniversary Weekend, a celebration set to feature former stars like Ichiro and Ken Griffey Jr.
The timing makes the latest adjustment feel especially inconvenient, even if these kinds of moves have become routine over a long season.

Cal Raleighs Sudden Drop Is Becoming A Real Mariners Concern
Cal Raleighs value to the Mariners has never been limited to what shows up in the box score, but his bat has become hard to ignore for all the wrong reasons. After a 2025 season that featured 60 home runs and a second-place finish in AL MVP voting, he has slid into a deep offensive slump, batting .162 with 12 homers and a .574 OPS while striking out more often and producing less authority on contact.
The timing makes it especially uncomfortable for Seattle, which is trying to keep its postseason push on track while leaning on Raleighs defense, leadership and right-handed power. An 0-for-38 skid and a right oblique injury that sent him to the injured list have only sharpened the concern, leaving the Mariners to wait and see whether their cornerstone catcher can find his timing again before the race tightens any further.
