2025 Fantasy Outlook
The Rays were able to flip Greg Jones, a position player with no long-term future with the club, to Colorado for Rock during spring training in 2024. Rock, a 6-foot-6 lefty with back-end starter potential, logged a 4.58 ERA, 1.40 WHIP and 132 strikeouts in 139.2 innings at Triple-A in his first year with his new club, and he was added to the 40-man roster after the season. He has an unremarkable 91-93 mph fastball and an above-average slider that allows him to have success against same-handed hitters. Rock's changeup is a fringe-average offering, and he might be better deployed following an opener where he can face as few righties as possible. The Rays have plenty of starting pitching depth, and Rock is one of their less appealing options, but he could be a deep-league streamer at some point in 2025. Read Past Outlooks

PTampa Bay Rays  AAA
July 6, 2025
The Rays optioned Rock to Triple-A Durham on Sunday.
Analysis
He'll be replaced on the 26-man roster by Joe Boyle, who had been starting for Durham and could serve as a swingman during the upcoming week. Rock made his MLB debut June 28, covering two innings while allowing two earned runs on four hits and striking out four. The lefty reliever went unused in the Rays' ensuing six games.

Stat Review
How does Joe Rock 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.
