Jackson Ferris threw an absolute gem Sunday night, racking up nine strikeouts in five scoreless innings for Triple-A Oklahoma City. This wasn’t just any good start; Ferris worked around four singles and a walk to deliver his best performance of the year, a much needed boost after a rough go for most of 2025. You love to see a young arm dial it in.
Ferris Finds His Groove and Other Arms Deliver
For real, this is a massive change-up from what Ferris was doing earlier this season. In his last seven outings, he’s rocking a 28.5-percent strikeout rate and an 8.9-percent walk rate. That’s a huge improvement when you compare it to his first 12 outings through the end of June, where he was sitting at 17 percent K-rate and a whopping 14.6 percent walk rate. His ERA has dropped too, from 7.87 to 5.30. That’s the kind of adjustment that makes you sit up and take notice. After Ferris, Bobby Miller came in with three scoreless innings and three strikeouts, and then Ben Casparius closed it out with a scoreless ninth, sealing Oklahoma City’s 5-0 win over Albuquerque. Talk about a lockdown bullpen!
Over in Double-A Tulsa, Patrick Copen was also dealing, striking out 10 in 6 2/3 innings. He gave up just one run on five hits and a walk as the Drillers beat the Arkansas Travelers 6-1. Yeah, that’s right, our boys in the Mariners affiliate system got a taste of Copen’s stuff. Josue De Paula homered for Tulsa, as did Joe Vetrano (who’s now gone yard three straight games, that’s wild) and Jake Gelof. Elsewhere, High-A Great Lakes saw Tyler Gough throw six scoreless innings with six strikeouts, but then things got sideways in the seventh after he left. And down in Class-A Ontario, the Tower Buzzers pulled off a miracle, scoring nine runs in the ninth inning to stun Rancho Cucamonga 10-5. Caleb Johnson hit his first professional home run, a grand slam in that wild ninth inning, and Conner O’Neal also homered earlier. What a finish!
What’s Next for the Minors and a Mariners Update
This is the kind of energy you want to see building in the minor league system, with guys finding their rhythm and stepping up. Oklahoma City is headed to Sugar Land to face the Astros’ affiliate next, while Tulsa takes on Amarillo. Great Lakes is off to Fort Wayne, and our Mariners’ Inland Empire boys are battling Ontario.
Speaking of our Mariners, how about a 3-2 road win against the Houston Astros? Yeah, that’s right, a tight one in enemy territory, and we pulled it off. Always good to see our big-league club grind out those W’s! Let’s keep that momentum rolling, Emerald City.
