Alberto (back) is listed among the White Sox's available relievers for Wednesday's Cactus League game against the Angels, Scott Merkin of MLB.com reports.

Alberto had been expected to make his most recent spring appearance Monday against the Rockies, but he ended up being scratched after contending with back tightness. After getting a couple days off to recover, Alberto looks to have moved past the issue. A Rule 5 selection over the winter, Alberto has struck out four batters and has allowed three earned runs through five innings this spring.

Selvidge recently underwent internal brace surgery on his left elbow and will miss the 2026 season, Jonathan Mayo of MLB.com reports.

Selvidge is one of the Yankees' better pitching prospects and flashed a fastball that reached 97 miles per hour earlier this spring before he suffered the elbow injury. He previously dealt with a pinched nerve in his biceps that required surgery in 2024. The 6-foot-3 southpaw turns 24 in August and logged 75 innings at Double-A last season, and he will probably return to Double-A when healthy in 2027.

The Mariners optioned Gonzalez to Triple-A Tacoma on Wednesday.

Gonzalez has made four Cactus League appearances, permitting one run with a 4:1 K:BB over four innings. The 26-year-old was a waiver claim from the Mariners last August and has yet to make his major-league debut.

Brash (mouth) is listed among the Mariners' available relievers for Wednesday's Cactus League game against the Rockies, Shannon Drayer of SeattleSports.com reports.

Brash will be making his first appearance of the spring after he had been delayed in his throwing progression during camp due to a tooth extraction he had a couple of weeks ago. Since Brash primarily functioned as a one-inning reliever for Seattle last season, he shouldn't require more than a handful of appearances in Cactus League games or on the back fields of Mariners camp over the next two weeks to ensure he'll be available for Opening Day.

The Angels reassigned Perdomo to minor-league camp Wednesday.

The 31-year-old lefty had been attending camp as a non-roster invitee but didn't appear in any Cactus League games before the Angels removed him from the competition for a spot in the Opening Day bullpen. Perdomo has previously seen big-league action in parts of four seasons from 2020 through 2025, accruing a 5.54 ERA and 1.44 WHIP across 14 appearances.

The Angels optioned Mederos to Triple-A Salt Lake on Wednesday.

Mederos entered the spring facing long odds to win a spot in the Angels' Opening Day rotation and didn't help his case by yielding six earned runs on seven hits and four walks across 4.1 innings between his two Cactus League outings. The right-hander should continue to make regular starts at Salt Lake to begin the season but won't necessarily be the Angels' first choice for a call-up if a spot in the big-league rotation opens up.

Brieske (ribcage) faced hitters in a simulated game Tuesday, Evan Petzold of the Detroit Free Press reports.

Brieske was lifted from his most recent spring appearance March 2 due to right ribcage tightness, but assuming he experienced no discomfort during Tuesday's sim game, he could be cleared to rejoin the Grapefruit League pitching schedule within the next few days. The right-hander will likely be in line for a low-leverage role out of the Detroit bullpen if he's able to secure a spot on the Opening Day roster.

Brash (mouth) could make his Cactus League debut as soon as Wednesday, Shannon Drayer of SeattleSports.com reports.

Brash is behind schedule following a tooth extraction, but his spring training debut is imminent. Barring something unexpected, the reliever should be fine for Opening Day. Brash is projected to serve as a setup man ahead of closer Andres Munoz this season.

Miller (back) is scheduled to make his Cactus League debut Friday against the Reds, Justice delos Santos of The San Jose Mercury News reports.

Miller threw a live batting practice session Tuesday with no issues, clearing the way for him to make his first appearance of spring training. The left-hander has been battling a back problem but expects to be ready to roll in time for Opening Day.

Abreu is expected to open the season as the Astros' closer while Josh Hader (biceps) recuperates, Chandler Rome of The Athletic reports.

Hader is throwing off the mound again and might not miss much time, but manager Joe Espada ruled him out for Opening Day. Abreu has been one of the best relievers in baseball over the past four regular seasons, posting a 2.30 ERA and 34.3 percent strikeout rate. Hader will get his closer job back, if healthy, but he remains an injury risk, so it's not out of the question that Abreu's stint as closer lasts indefinitely.
