The Rays and White Sox announced a one-for-one trade that sends lefty reliever Joe Rock from Tampa Bay to Chicago. Minor league infielder Oliver Dunn goes to the Rays; Dunn had not been on Chicago’s 40-man roster.
Chicago optioned Rock to Triple-A Charlotte and transferred Kyle Teel to the 60-day injured list to open a 40-man spot. That’s a procedural move, as the 60-day window backdates to Opening Day. Teel won’t be back until late June at the earliest after suffering an LCL sprain in his left knee over the weekend.
A 6’6″ southpaw, Rock was a second-round pick by Colorado in 2021. The Rays acquired him in Spring Training 2024 for former first-rounder Greg Jones. Rock spent that season working out of the Triple-A rotation, struggling to a 4.58 earned run average. He made a very brief MLB debut last summer, pitching 7 2/3 innings of two-run ball with 11 strikeouts over three appearances.
Rock otherwise spent the season in a swing role in Triple-A, posting a 5.21 ERA across 96 2/3 frames. The Rays moved him to short relief this year in the hope that his stuff would play up in 1-2 inning stints. Rock has missed more bats, striking out 27 of 78 opponents (34.6%) in the minors.
His 92.9 mph average fastball isn’t much above where it sat last year, though, and Rock has battled the worst control of his career. He has walked 17 batters and plunked four more, giving out free passes to more than a quarter of batters faced. Rock has allowed 10 runs (nine earned) through 15 Triple-A innings this year.
The lack of strikes had pushed the Ohio University product to the fringe of the roster. The Rays didn’t designate Rock for assignment but had soured enough on him that they were willing to deal him for a depth infielder on a minor league contract. Chicago will see if a change of scenery can get him on track. Rock is in his second of three option years, so there’s still some roster flexibility.
Sean Newcomb and Bryan Hudson have pitched well as Will Venable’s top two lefty relievers. The Sox brought Brandon Eisert back up from Charlotte last week as a third southpaw in the MLB bullpen. Tyler Schweitzer, Tyler Gilbert and Chris Murphy are on the 40-man roster and on optional assignment. The Sox certainly aren’t lacking left-handed bullpen arms.
Dunn is a 28-year-old utilityman who appeared at the MLB level with the Brewers from 2024-25. The lefty batter owns a .206/.261/.290 slash with one home run in 145 career plate appearances. Milwaukee sent Dunn unclaimed through waivers last September and allowed him to walk as a minor league free agent. He signed a non-roster deal with the Sox in December.
After struggling to a .208/.315/.338 line in Triple-A a year ago, Dunn has gotten out to a much better start this season. He hit .296/.397/.533 with eight homers in 40 games for Charlotte. Dunn takes a lot of pitches and had shown strong on-base numbers up through Double-A. He’s primarily a third baseman who can play the middle infield if necessary and has some left field experience in the minors.
The Rays recently lost one of their left-handed bench bats when Jake Fraley suffered a sports hernia injury that required surgery. They’re also a little shorthanded in the infield with Ben Williamson day-to-day with back tightness. Tampa Bay might add Dunn directly to the MLB bench if Williamson requires an injured list stint. They don’t have any depth infielders on optional assignment to Triple-A, and Dunn has outhit internal depth pieces Logan Davidson and Raynel Delgado. Tampa Bay has a pair of openings on the 40-man roster if they want to select Dunn’s contract.
What about his brother, The.
He’s busy making questionable choices in his movie career.
He’s not doing so hot.
His brother Pete, on the other hand…
As Danhausen would say, Rock “The Dwayne” Johnson.
very nice
Boooooooooooooooooooooo
Finally.
Joe has been getting rocked in AAA but Dunn has never done much.
There goes Rock
