Latest news
The Athletics placed Jump on the 15-day injured list Tuesday, retroactive to Sept. 13, due to a left shoulder impingement.
The A's have already been eliminated from playoff contention, so the move to the IL will officially bring an end to Jump's 2026 campaign. The left-hander finishes his rookie year having gone 6-11 in 20 starts with a 5.47 ERA, 1.52 WHIP and 108:46 K:BB across 98.2 innings. He should compete for a rotation spot during spring training but likely won't enter camp with a guaranteed role.

Jump (shoulder) is likely to be placed on the 15-day injured list, Jason Burke of Roundtable.io reports.
Jump was dealing with left shoulder tightness during his last start Saturday against the Mariners. Whether he goes on the IL will be determined Tuesday, but if that is indeed the route that is chosen, then Jump's 2026 season will likely be over. Across 20 starts, Jump has a 6-11 record with a 5.47 ERA, 1.52 WHIP and 108:46 K:BB over 98.2 innings.

Manager Mark Kotsay said after Saturday's game against the Mariners that Jump has a shoulder impingement and will be re-evaluated Sunday, Theo DeRosa of MLB.com reports.
The left-hander felt some tightness while throwing in the bullpen prior to Saturday's start, but he pitched through it and was dealt his 11th loss of the campaign after giving up five runs across two innings. The A's figure to be cautious with Jump down the stretch as his rookie campaign nears the finish line.

Jump (6-11) allowed five runs on five hits, a walk and a hit batsman while striking out two over two innings to take the loss Saturday versus the Mariners.
Jump didn't have it from the beginning in this game, throwing 28 of 44 pitches for strikes. He gave up a pair of home runs to account for all five runs on his line in his shortest start of the season. Over his last five games, he's allowed 21 runs across 20.2 innings, though he has a 23:9 K:BB in that span. Overall, he's at a 5.47 ERA, 1.52 WHIP and 108:46 K:BB through 98.2 innings over 20 starts. Expect the rookie southpaw to take the mound in Cleveland for his next start, but between performance and workload, he appears to be on a short leash.

Jump (6-10) allowed two runs on six hits and struck out seven without walking a batter over four innings to take the loss versus the Mariners on Sunday.
Jump wasn't particularly efficient, needing 82 pitches (60 strikes) to get through his four frames. He's fallen short of the five-inning mark in four of his last seven outings, giving up 27 runs over 33.2 innings with a 38:20 K:BB in that span. The 23-year-old southpaw is at a 5.12 ERA, 1.49 WHIP and 106:45 K:BB through 96.2 innings over 19 starts in the majors this year. He has totaled 134.2 innings between the majors and Triple-A in 2026, up from 111.2 frames between Double-A and High-A in 2025, so there may be some intent from the Athletics to keep his outings short. He's tentatively projected to make his next start at home in a rematch with the Mariners.
