2025 Fantasy Outlook
If you squint really hard, you can see some shades of Ryan Yarbrough in Lopez. Both pitchers are soft-tossing lefties with unique arm angles relying on extension and guile in their efforts to be successful against opposing batters. Lopez has been able to use that skill rather effectively as a minor leaguer with a 30.6% strikeout rate but has been more hittable as a swingman in two different stints with the Rays over a short 22.2 inning sample size. Lopez has value to the club in a swingman type role or as a bulk pitcher if the rotation is once against impacted with injuries. The rotation is projected to be in tact and deep coming into the season, so Lopez's role will likely need to be out of the pen as he competes against the likes of Cleavinger and Montgomery for a lefty role in the pen.

$Signed a one-year contract with the Rays in March of 2024. Traded to the Athletics in December of 2024.
Headed west after swap
POakland Athletics
December 14, 2024
The Rays traded Lopez and Jeffrey Springs to the Athletics on Saturday in exchange for Joe Boyle, Jacob Watters, Will Simpson and a compensatory draft pick.
ANALYSIS
Lopez appeared in four games for the Rays last season, giving up six earned runs while striking out eight batters and walking seven across 10.1 innings. His performance improved slightly in Triple-A (4.26 ERA, 1.32 WHIP over 88.2 innings), and his chances of making the Athletics' Opening Day bullpen will likely depend on how well he does during spring training.

Stat Review
How does Jacob Lopez 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.

2024 Fantasy Outlook
Lopez began the season at Double-A Montgomery and finished it with four games on the big-league roster, which is a rarity for the Tampa Bay organization as it rarely promotes starting pitchers multiple levels in the same season. These actions were more based on necessity than merit given the season-ending injuries to 60 percent of the club's starting staff and the attrition of arms on the 40-man roster. Lopez climbed to Triple-A early in the 2023 season while striking out a bevy of lower-level hitters, mainly with a low-arm-slot slider. Experienced hitters in Triple-A were not as easily fooled nor were the major-league hitters as the strikeout rate cooled and the walk rate escalated. He still managed 96 strikeouts in 92 innings but best profiles as a swingman out of the bullpen, replacing the role Ryan Yarbrough and Josh Fleming held on the roster before him.
