Our Mariners Exposed Aaron Civale's Dead Arm, And The A's Are Now Calling Up Gage Jump To Save Their Season

Alright, Emerald City! You already know Monday night was a blast, right? Our Seattle Mariners absolutely clobbered the A's 9-2, and guess what? We didn't just win a game, we broke their starting pitcher! Yeah, you heard me. Aaron Civale, who got shelled by our boys, is headed to the injured list, and the A's are in full panic mode, reportedly calling up top prospect Gage Jump. This is wild, and it all went down after our M's got to him!

Aaron Civale's Right Shoulder is Toast, Thanks to Our M's

Let's talk about the guy who had a really bad night against our Mariners. Aaron Civale got pulled after only four innings on Monday, and it was obvious something was off. His fastball velocity was garbage, averaging a pathetic 88.3 mph on the stadium radar gun. That's more than 3 mph *slower* than his 2026 season average! Manager Mark Kotsay wasted no time saying the problem was Civale's right shoulder or lat. Dude, that’s a red flag waving in the wind. Civale will undergo testing today, but the damage is done. He was cooked, straight up. Against our Mariners, Civale allowed seven runs on nine hits and one walk, throwing only 73 pitches in that ugly 9-2 loss. And get this, he was also working through an arm issue "for a little bit" before facing our guys and the Angels last week. He gave up five runs in five innings to the Angels, too. Before these two brutal starts, his ERA was a respectable 2.70. Now, after surrendering 14 hits, six home runs, and 12 earned runs in those two games, his ERA stands at 4.20 through 11 starts. Our Mariners exposed him, plain and simple.

Can Gage Jump Actually Help the A's?

So, with Civale's arm officially busted, the A's are reportedly turning to Triple-A Las Vegas for help. Their top prospect, 23-year-old left-hander Gage Jump, is getting the call-up. Jump is a strikeout pitcher, fanning 56 batters in 38 innings over nine starts this season. That's solid, but he's also walked 20 batters and holds a 4.50 ERA with an 0-2 record. He was a second-round pick out of LSU in 2024 and is ranked No. 41 overall in baseball by MLB Pipeline. That's high praise, but he's still a prospect, even if he's third among the A's prospects behind shortstop Leo De Vries and another LHP, Jamie Arnold. Arnold, by the way, was the 11th overall pick in 2025 and is currently pitching at Double-A Midland. Can a 23-year-old lefty really stabilize a rotation after our Mariners just blew it up? We'll see. This is exactly what we love to see: our Mariners making other teams sweat and forcing them to scramble. While the A's are desperately trying to patch up their rotation, our boys are out here doing what they do best, winning games and showing the league what Emerald City baseball is all about. Keep that momentum rolling, M's! Let's go!
