Brieske (ankle) began a throwing program Tuesday, Chris McCosky of The Detroit News reports.

Brieske landed on the 15-day injured list last Friday with right ankle inflammation but is ready to start ramping things up. The reliever is eligible to return in early May.

Brebbia (triceps) has resumed a throwing program, Chris McCosky of The Detroit News reports.

Brebbia just landed on the 15-day injured list this past weekend with a right triceps strain, so it's a good sign that he's already playing catch. The reliever will be eligible for activation May 4, and it would seem he has a shot to be ready at that time.

The Tigers recalled Lee from Triple-A Toledo on Tuesday, Cody Stavenhagen of The Athletic reports.

Lee, 26, held a 6.75 ERA but a 12:3 K:BB over his first 9.1 frames with Toledo this season. The right-handed reliever will be making his major-league debut when/if he gets into a game.

The Red Sox optioned Kelly to Triple-A Worcester on Tuesday.

He's clearing out to make room on the roster for the return of Brayan Bello (shoulder). Kelly has permitted 10 runs over 10 innings this season, although that's come with an 11:2 K:BB. He'll get another opportunity later on this season.

The Guardians transferred Stephan (elbow) to the 60-day injured list Tuesday.

The move frees a spot on the 40-man roster for Will Wilson, who was called up Tuesday. Stephan is still working his way back from UCL reconstruction surgery and the shift to the 60-day IL doesn't alter his timetable.

Lawrence cleared waivers and was outrighted to Triple-A Tacoma on Tuesday.

The right-hander was designated for assignment over the weekend by the Mariners for the second time in April, but he'll again stick in the organization after passing through waivers unclaimed. Lawrence has given up two earned runs with a 1:1 K:BB over five frames in the majors this season and has a 4.35 ERA across 10.1 innings as a starter for Tacoma.

Triple-A Columbus placed Walters on its 7-day injured list Monday due to an unspecified injury.

After failing to win a spot in the Guardians' Opening Day bullpen coming out of spring training, Walters had gotten off to a strong start to the season with Columbus, producing a 1.35 ERA, 1.20 WHIP and 13:5 K:BB in 6.2 innings over seven appearances. However, the right-hander sustained an apparent injury during his most recent appearance Wednesday, temporarily halting any momentum he might have built for a promotion to the big leagues.

The Red Sox will option Kelly to Triple-A Worcester prior to Tuesday's game against the Mariners, Chris Cotillo of MassLive.com reports.

The transaction will clear a spot on the active roster for Brayan Bello (shoulder), who is slated to make his season debut. Kelly boasts an 11:2 K:BB over 10 innings this season but has also surrendered 10 runs across his seven appearances.

Triple-A Scranton/Wilkes-Barre placed Arias on the 7-day injured list March 28.

The hard-throwing righty was dealt from the Cubs to the Yankees in exchange for cash in January after the Cubs had designated Arias for assignment. The days of Arias starting are over, but he had eight strikeouts and one walk in five one-inning spring training appearances and could develop into a high-leverage reliever in a couple years.

The Orioles placed Poteet on the 15-day injured list Tuesday with right shoulder inflammation.

Poteet was rocked for five runs while throwing 68 pitches over 2.2 innings in Sunday's blowout loss to the Reds and apparently came out of the appearance with a shoulder problem. It's not clear how long he might be sidelined.
