Campbell was placed on the 7-day injured list at Triple-A Worcester on Tuesday with right elbow inflammation, Chris Cotillo of MassLive.com reports.

It's not clear how long Campbell might be sidelined, but certainly he won't be an option for Boston's bullpen anytime soon. The 26-year-old has been tagged for 13 runs (12 earned) over 6.2 innings with the Red Sox this season but has pitched well at Worcester, holding a 2.20 ERA and 19:5 K:BB across 16.1 frames.

Holton will start Tuesday's game against the Guardians, Jason Beck of MLB.com reports.

Holton will be the first reliever to take the mound for the Tigers during what's slated to be a bullpen game. The 28-year-old isn't likely to work more than three innings before handing the ball off.

Topa (knee) will start a rehab assignment with Single-A Fort Myers on Tuesday, Brandon Warne of Access Twins reports.

Topa hasn't played in 2024 due to a tear in the patellar tendon of his left knee, but he'll see his first in-game action since being returned from a rehab assignment in early May. The reliever will likely need several rehab appearances before being activated, and it's likely he won't be back in action until August.

The Rays claimed Kuhnel off waivers from the Brewers on Tuesday, Marc Topkin of the Tampa Bay Times reports.

The right-hander was designated for assignment by Milwaukee over the weekend, and Tampa Bay didn't waste any time scooping him up on waivers. Kuhnel has made just one appearance in the majors this season (with the Astros), but he's pitched well at the Triple-A level with a 2.30 ERA, 1.28 WHIP and 17:8 K:BB across 27.1 innings.

Garcia (5-1) earned the win over Seattle on Monday, allowing one hit and striking out two batters over one scoreless inning in relief.

All-Star Tyler Anderson gave the Angels 5.2 innings of one-run ball but received no offensive support while he was in the game. Garcia entered in the eighth with the game tied 1-1 and was effective despite throwing just 10 of 19 pitches for strikes, as he yielded only an infield single and fanned the final two batters he faced. The righty reliever then moved into position for the victory when Los Angeles scored twice in the top of the ninth. Garcia has been one of the team's top high-leverage options this season and has been very effective of late, posting a 1.32 ERA, 0.95 WHIP and 11:4 K:BB over his past 13.2 innings spanning 12 appearances. He's notched four wins and five holds over that span.

Stanek recorded a hold in a loss to the Angels on Monday, allowing an earned run on two walks over one-third of an inning. He struck out one.

Stanek had another worrisome outing, yet he still came out of it with a counting stat in the form of his 15th hold of the season. The right-hander took his third loss against the Astros on Saturday after blowing a 2-1 lead; Monday, he walked the first two batters he faced before striking out Nolan Schanuel prior to being swapped out for Andres Munoz, who gave up a game-tying sacrifice fly to Taylor Ward that resulted in a run being charged to Stanek. The 32-year-old Stanek has now allowed at least one earned run in three consecutive appearances, the first time that's transpired this season.

The Rays optioned Zuber to Triple-A Durham on Tuesday, Ryan Bass of Bally Sports Sun reports.

Zuber was with the Rays for two days, allowing one run over 1.2 innings in a relief appearance Monday versus the Yankees. He's being replaced on the roster by Tyler Alexander, who will handle bulk relief duties Tuesday in Toronto.

Single-A Kannapolis placed Taylor on its 7-day injured list June 12 and transferred him to its 60-day injured list June 16 while he recovers from a lat injury, Bill Mitchell of Baseball America reports.

The White Sox selected Taylor in the second round of the 2023 First-Year Player Draft while he was already on the mend from Tommy John surgery. He has a high ceiling, and that was on display during his brief stretch of full health, as the 22-year-old righty had a 1.13 ERA, 0.63 WHIP and a 25:1 K:BB in 16 innings across four starts for Kannapolis before succumbing to another injury.

Espino (undisclosed) has given up seven earned runs on 10 hits and one walk while striking out three over 5.2 innings in his two starts since being reinstated from Triple-A Buffalo's 7-day injured list July 4.

Espino missed a little over three weeks with the unspecified injury. The 37-year-old right-hander made two appearances out of the Toronto bullpen in April and retains a spot on the Blue Jays' 40-man roster, but he hasn't made a compelling case for another call-up after turning in a 5.80 ERA and 1.56 WHIP over 45 innings since returning to Buffalo.

Armstrong will serve as the Rays' opening pitcher for Tuesday's game against the Blue Jays, Marc Topkin of the Tampa Bay Times reports.

Armstrong will draw his sixth opener assignment of the season and is unlikely to work more than an inning or two Tuesday before exiting the game. The Rays plan to call up lefty Tyler Alexander from Triple-A Durham ahead of Tuesday's contest, and he'll be in line to work in bulk relief behind Armstrong.
