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.

The Padres recalled Jacob from Triple-A El Paso on Tuesday.
Analysis
Jacob was sent down to Triple-A at the end of August after throwing 4.2 shutout innings in three appearances, and he'll now rejoin the big-league bullpen following Jason Adam's (quad) move to the injured list. Although his most recent showing in the majors was successful, Jacob's 5.40 ERA through 30 innings will likely limit him to low-leverage work.

Stat Review
How does Alek Jacob compare to other relievers?
This section compares his stats with all relief pitcher seasons from the previous three seasons (minimum 30 innings)*. The bar represents the player's percentile rank. For example, if the bar is halfway across, then the player falls into the 50th percentile for that stat and it would be considered average.

* Exit Velocity, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against 2019 data (min 30 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.
