26-Year-Old PitcherRP
San Diego Padres AAA
2025 Fantasy Outlook
Jacob spent most of the 2024 season in Triple-A and posted a mediocre 5.53 ERA over 53.2 innings, but he impressed during his time in the majors, recording a 19:2 K:BB in 14.2 frames across seven appearances. The right-hander added a 2.45 ERA and 0.75 WHIP and was effective enough to be on San Diego's roster for the NLDS. Jacob doesn't profile as a high-leverage reliever due to his lack of his velocity -- his fastball sits in the high-80s -- but he induces plenty of whiffs (and, consequently, punchouts) thanks to a funky, deceptive delivery and a mid-to-low-70s changeup that opponents batted just 3-for-20 against last season. Jacob tossed two or more innings in five of his seven outings with San Diego in 2024, so the organization may be viewing him as primarily a middle-relief arm. Read Past Outlooks
$Signed a one-year contract with the Padres in March of 2025.
Returns to minors
PSan Diego Padres  AAA
May 25, 2025
The Padres optioned Jacob to Triple-A El Paso on Sunday.
ANALYSIS
Jacob has been up with San Diego all season and had been pitching decently with a 3.34 ERA through 20 appearances, but he surrendered 10 earned runs over his past two outings, including four runs Saturday in Atlanta. The right-hander will head to the minors in favor of Omar Cruz, who will bolster the Padres' bullpen depth.
