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.
Enjoys best start of career
Jump (3-1) earned the win over the Angels on Thursday, allowing one hit and issuing three walks while striking out seven batters over seven scoreless innings.
Analysis
The Angels simply couldn't get to Jump, managing just one hit -- an Oswald Peraza double -- against him. The rookie left-hander established a career-best mark with seven punchouts and tossed his second scoreless start over his past three outings. Jump has yet to give up a homer through five appearances this season, and he's completed at least six innings in three of those starts. Jump appears to be in the big-league rotation to stay, as he's registered an excellent 2.37 ERA and 0.99 WHIP along with a 26:9 K:BB through his first 30.1 major-league frames.
