2026 Fantasy Outlook
Jump, who the Athletics selected No. 73 overall in 2024, generated a lot of buzz in the first half of 2025 but faded a bit down the stretch. He had a 13.50 ERA, 2.32 WHIP and 12:7 K:BB in 13.1 innings over his final four starts, finishing with a 3.64 ERA, 1.20 WHIP and 86:29 K:BB in 81.2 innings at Double-A. The 6-foot lefty got up to 112.2 innings on the year after throwing 83 innings in 2024 at LSU. He had Tommy John surgery in 2023. At his best, Jump's deceptive delivery allows his 92-94 mph fastball (which touches 97 mph) to play up as a plus pitch. Evaluators differ on whether Jump has any other plus pitches, but his slider and curveball get strong reviews, while his fourth-pitch changeup is passable. The A's have spared Jump from an assignment to the unforgiving Pacific Coast League, but he will have to check that box of his development before he joins the big-league rotation. He has mid-rotation upside and would be more appealing in starts away from Sutter Health Park in the short term. Read Past Outlooks
Signed a one-year contract with the Athletics in May of 2026.
Takes loss in MLB debut
Jump (0-1) allowed four runs on nine hits and one walk while striking out five batters over five innings in a loss to Seattle on Tuesday.
Analysis
Jump was added to the 40-man and 26-man rosters ahead of Tuesday's contest and made his first appearance as a major leaguer. The left-hander retired the first three batters he faced but then had a rough second inning, giving up three runs on four hits and a walk. Jump gave up another run on five hits and a hit-by-pitch over the following two frames but did manage to finish the start with a 1-2-3 fifth inning. He displayed decent strikeout stuff overall, notching 13 whiffs and five punchouts. Jump could be lined up for additional starts while Aaron Civale (shoulder) remains on the injured list.
