The A's are making the call. According to ESPN's Jeff Passan, No. 3 prospect Gage Jump is headed to Sacramento. This is something that every A's fan was clamoring for after his last start on May 20, where he went seven scoreless innings, giving up four hits and striking out nine. 

While the A's have plenty of recent history calling up big-name prospects, all of those have been on the offensive side of the ball. With Jump, he's the first big-time prospect to get called up early in the season in the past couple of years. Of course, there was Mason Miller back in 2023, who was flying under the radar, even as the No. 4 prospect in the system.

Jump won't have that luxury. His 97 mph heater from the left side has already turned heads nationally, and the numbers back it up, with 56 strikeouts in just 38 innings, a 33.1% strikeout rate.

While this is the biggest move the A's could have made, it does come with one caveat: He's not on the 40-man roster, which means a cut will have to be made — or Civale's injury is a serious one. 

After Aaron Civale gave up seven earned runs on nine hits and a walk across just four innings on Monday, A's manager Mark Kotsay began the postgame press conference by saying that the righty would be undergoing some tests on Tuesday morning.

"Aaron's been grinding right now, and we're gonna get some tests done tomorrow morning. Most likely headed to the IL."

Kotsay was asked to elaborate on what type of injury he's been dealing with, and attempted to describe it vaguely at first, before saying that he couldn't comment on the injury. 

Civale's velocity was down on Monday night in Sacramento, with his cutter down 1.9 mph, but his other four offerings down between 3.0–3.2 mph. That also led to less spin on his pitches, which meant less movement on his offerings, and more loud contact from the Seattle Mariners offense. 

Notably, his velocity started low and held there with no mid-game cliff. Just a flat, diminished baseline all night. 

His velocity had been down a touch in his last start against the Los Angeles Angels as well, with his cutter down 0.3 mph. His sinker and four-seamer were each down 1.2 and 1.3 mph, but were thrown a combined 11 times, which isn't a huge sample size to work off to determine anything. 

Still, he's given up six home runs in his past two games and eight in his last three. We'll know more about Civale's status on Tuesday.
