The Orioles transferred Poteet (shoulder) from the 15-day injured list to the 60-day IL on Friday.

The right-hander has been on the shelf since late April due to shoulder inflammation, and he'll remain sidelined for at least a few more weeks. Poteet surrendered five runs over 2.2 frames in his lone outing for Baltimore before landing on the IL.

The White Sox placed Castro on the 15-day injured list Friday due to a torn patellar tendon in his right knee.

Castro suffered the injury during Wednesday's game against the Mets and is set to miss the rest of the season, and it's unclear if he'll be ready for the start of the 2026 campaign. The right-hander will likely be shifted to the 60-day IL once Chicago needs an opening on the 40-man roster.

Altavilla agreed to a one-year, $1 million contract with the White Sox on Friday.

The veteran right-hander was released from his minor-league contract with the White Sox last weekend, but he's now back with the club on a major-league deal. Altavilla pitched well for Triple-A Charlotte with a 2.49 ERA, 1.32 WHIP and 18:10 K:BB across 21.2 innings.

The Orioles placed Mullins on the 10-day injured list Friday, retroactive to May 29, due to a right hamstring strain.

It's not yet known when exactly Mullins suffered the injury, but he sat out two games at the start of the week for rest purposes before rejoining the lineup Wednesday against the Cardinals, and he went 2-for-4 with a steal and two runs in that contest. According to Danielle Allentuck of TheBaltimoreBanner.com, the outfielder was diagnosed with a mild strain and could return when first eligible June 8. Cooper Hummel was added to the big-league roster in a corresponding move, and he could see action in center field while Mullins is out, along with Dylan Carlson and Jorge Mateo.

The Rays activated Mangum (groin) off the 10-day injured list Friday, Ryan Bass of FanDuel Sports Network Sun reports.

The 29-year-old has been sidelined by a groin strain for over a month, but he's ready to rejoin the Rays after going 9-for-21 with four walks and a double during a six-game rehab assignment. Mangum wasn't expected to be a factor for Tampa Bay to begin the season, but he took advantage of the club's outfield injuries and started his MLB career with a strong .338/.384/.397 slash line and eight steals in his first 21 games.

The Rays optioned Simpson to Triple-A Durham on Friday, Ryan Bass of FanDuel Sports Network Sun reports.

The 24-year-old speedster enjoyed a strong start to his big-league career with a .285 batting average, 19 steals, 11 RBI and 17 runs in his first 35 games, but he's being demoted Friday with Jake Mangum (groin) making his return from the injured list. It's likely only a matter of time before Simpson rejoins the Rays this season, but for now he'll return to Durham, where he may focus on improving his defense after posting minus-5 DRS and minus-3 OAA in 284 outfield innings.

Clase went 2-for-4 with a walk, two runs scored and a stolen base in Thursday's rout of the A's.

Getting the start in left field and batting eighth, Clase continued to flash impressive on-base skills while stealing his third bag in three attempts over 12 games in the majors this season. The 23-year-old outfielder has hit safely in each of his last six games dating back to May 18, batting .500 (8-for-16) with three RBI, four runs and a 5:3 BB:K.

Guerrero went 1-for-4 with a two-run home run in Thursday's rout of the A's.

The majestic second-inning blast over the left-field fence came off Jacob Lopez, and while it only traveled 399 feet, the ball reached a height of 136 feet after leaving Guerrero's bat with an eye-popping launch angle of 37 degrees. It was Guerrero's eighth homer of the year and his fourth in the last 14 games -- a stretch in which he's slashing .240/.367/.480 with six RBI, nine runs and a 9:4 BB:K.

Springer went 2-for-5 with a solo home run and an additional run scored in Thursday's 12-0 win over the A's.

Springer launched Toronto's fourth homer of the game in just the third inning Thursday, a 376-foot shot off Anthony Maldonado to extend the Jays' lead to 11-0. It's the sixth home run this season for Springer, who'd gone just 1-for-15 in his previous six contests. Still, it's been a strong bounce-back campaign thus far for the veteran outfielder -- Springer's slashing .250/.367/.445 with 26 runs scored, 19 RBI and seven stolen bases across 196 plate appearances.

Shuster will work as the opener Friday in Baltimore, Scott Merkin of MLB.com reports.

The game got pushed up a few hours due to inclement weather, so Shuster is going to give primary pitcher Sean Burke more time to get ready. Shuster has been back and forth between Triple-A and the majors a couple times this month, and he has a 1.93 ERA, 1.71 WHIP and 3:2 K:BB in 4.2 innings over his three most recent appearances with the big club.
