Orioles manager Brandon Hyde said Monday that Kittredge (knee) will throw a live batting practice session Wednesday, Jake Rill of MLB.com reports.

Kittredge will face hitters for the first time since he underwent arthroscopic surgery on his left knee during spring training. The veteran reliever's rehab has some along more quickly than anticipated and he could be ready to return from the 15-day injured list before the end of May.

The Blue Jays transferred Burr (shoulder) from the 15-day injured list to the 60-day IL on Sunday.

Toronto replaced Burr on the 40-man roster with right-hander Casey Lawrence, whom the club claimed off waivers from Seattle on Monday. As a result of his move to the 60-day IL, Burr -- who has been on the shelf all season while recovering from right shoulder inflammation -- won't be eligible to make his 2025 debut until late May. Burr recently resumed throwing off a mound, but he's likely a week or more away from heading out on a minor-league rehab assignment.

The Blue Jays claimed Lawrence off waivers from the Mariners on Monday.

Toronto has plenty of familiarity with Lawrence, a 37-year-old journeyman who signed with the Blue Jays as an undrafted free agent in 2010 before he reached the big leagues for the first time in 2017. Before being designated for assignment by Seattle over the weekend, Lawrence had filled a swingman role in the majors and at Triple-A Tacoma, making four relief appearances for the big club and two starts in the minors. Since he has no minor-league options remaining, Lawrence will join Toronto ahead of its three-game series with the Red Sox that begins Tuesday, but it's not immediately clear whether he'll work out of the bullpen or slot into the rotation. The Blue Jays have a starting spot open for Wednesday after demoting Easton Lucas, who had been filling in for the injured Max Scherzer (thumb).

Gilbert will serve as the White Sox's opening pitcher in Tuesday's game versus the Brewers, Scott Merkin of MLB.com reports.

He's expected to be followed by Bryse Wilson in bulk relief in what will be Gilbert's third straight appearance as an opener. He's tossed a scoreless frame in both of the first two assignments and should be in line for a similar workload Tuesday.

The Guardians recalled Bolton from Triple-A Columbus on Monday, Tim Stebbins of MLB.com reports.

Bolton will provide a fresh relief arm after the Guardians had a doubleheader over the weekend. The 26-year-old holds a 5.40 ERA and 39:24 K:BB over 40 career frames at the big-league level.

The Guardians optioned Cantillo to Triple-A Columbus on Monday, Tim Stebbins of MLB.com reports.

Cantillo has pitched well out of the Guardians' bullpen this season, posting a 2.35 ERA and 20:8 K:BB over 15.1 innings. Cleveland's bullpen has been taxed recently -- Cantillo threw 55 pitches in Sunday's loss to Boston -- and needed a fresh arm.

The Orioles recalled Strowd from Triple-A Norfolk on Monday.

The Orioles are swapping out one reliever for another, sending down Grant Wolfram while bringing up Strowd. The 27-year-old righty holds an 8.10 ERA but an 18:4 K:BB over 10 innings this season at Norfolk. Strowd will be making his major-league debut when/if he gets into a game.

The Orioles optioned Wolfram to Triple-A Norfolk on Monday.

Wolfram had pitched each of the last two days, allowing two runs on three hits and two walks over 1.1 innings. Kade Strowd will take his spot on the roster and in the bullpen.

Enright (lat) issued three walks over a scoreless inning of relief Sunday for Triple-A Columbus after being activated from the 7-day injured list Friday.

Enright struggled to find the strike zone in his 2025 debut, but he was able to get himself out of a jam after loading the bases in the sixth inning. The right-hander had opened the season on Columbus' IL after he sustained a low-grade right lat strain prior to reporting to spring training. He possesses a spot on the Guardians' 40-man roster but is unlikely to be in the mix for a call-up anytime soon.

Guardians manager Stephen Vogt said Sunday that Stephan (elbow) is "progressing well" and is expected to return to game activity at the organization's spring training complex in Arizona at some point in May, Michael Beaven of the Akron Beacon Journal reports.

Stephan missed the entire 2024 season while recovering from UCL reconstruction surgery, which he underwent last March. Now more than a year removed from the procedure, Stephan has reached the point in his recovery program that he's facing hitters, and he'll likely soon test himself in a simulated-game setting in Arizona before reporting to an affiliate for a rehab assignment. The right-hander was a key piece of the Cleveland bullpen in his last healthy season in 2023, turning in a 4.06 ERA, 1.30 WHIP and 75:26 K:BB while collecting seven wins, 30 holds and two saves over 71 appearances.
