Wilson earned the save in Friday's 4-1 win over Texas. He issued one walk without allowing a hit and didn't record a strikeout in a scoreless ninth inning.

With Cam Booser and Jordan Leasure dispatched for the seventh and eighth innings, respectively, the White Sox turned to Wilson to close things out in the ninth. Wilson needed 17 pitches (11 strikes) to maneuver through the frame and came away with his first save since 2022 as a member of the Padres. The 30-year-old right-hander has a 1.72 ERA, 0.89 WHIP and 13:8 K:BB across 15.2 innings this season.

The Red Sox added Criswell to their active roster to serve as the 27th man for Friday's doubleheader against Baltimore, Ian Browne of MLB.com reports.

Criswell hasn't performed well with the Red Sox this season, allowing five earned runs in only 4.1 innings, but he owns a 1.99 ERA across 22.2 frames at Triple-A Worcester. He'll give Boston some extra bullpen depth for Friday's twin bill but is likely to return to the minors following the second game.

The Mariners recalled Castano from Triple-A Tacoma on Friday.

Castano joins the Mariners' bullpen for what will be his MLB debut if he gets into a game. The 26-year-old will likely serve as a multi-inning reliever considering seven of his 10 appearances with Tacoma were starts. Castano has logged a 3.43 ERA and a 28:19 K:BB in 44.2 innings at Triple-A.

The Athletics optioned Duran to Triple-A Las Vegas on Friday, Martin Gallegos of MLB.com reports.

Duran made his MLB debut Thursday against the Angels and allowed three earned runs on one hit and three walks. He recorded just one out and will head back to the minors.

The Mariners designated Hahn for assignment Friday, Shannon Drayer of SeattleSports.com reports.

Hahn has given up four runs (three earned) with a 3:5 K:BB over five innings this season with the Mariners. He wound up re-signing with Seattle after being removed from its 40-man roster in April, but it's not clear what his intentions are this time around.

The Athletics recalled Lopez from Triple-A Las Vegas on Friday, Martin Gallegos of MLB.com reports.

Lopez is expected to start Friday against the Phillies, as J.T. Ginn (quadriceps) recently landed on the 15-day injured list. Lopez made a spot start against the Rangers back on April 29, allowing three earned runs on six hits and four walks across 2.2 innings of work. He struck out four and took the loss. Lopez could make multiple starts for the Athletics while Ginn is sidelined.

The Tigers optioned Guenther to Triple-A Toledo on Friday, Evan Petzold of the Detroit Free Press reports.

Guenther has yielded seven runs (six earned) with an 8:5 K:BB over 10.1 innings with the big club this season. He's clearing out to make room on the roster for the return of Matt Vierling (shoulder).

The Mariners outrighted Lawrence to Triple-A Tacoma on Friday.

Lawrence cleared waivers after being designated for assignment earlier in the week. The 37-year-old appeared in five games out of the bullpen for Seattle, logging a 3.00 ERA and 6:1 K:BB across 15.1 innings.

Speier allowed one hit in a scoreless inning with no strikeouts during Thursday's 9-2 loss to the Astros.

Speier turned in his seventh scoreless outing out of nine appearances in May. On the season, the 30-year-old owns a 2.25 ERA, 0.90 WHIP and 28:4 K:BB with seven holds over 20 innings. Speier has been one of Seattle's top high-leverage options as the team's lone left-hander, locking into a setup role ahead of closer Andres Munoz.

Zeferjahn recorded a hold against the Athletics on Thursday, allowing one hit and issuing one walk while striking out one batter in one scoreless inning.

Zeferjahn entered in the eighth inning with the Angels up two runs and quickly got into trouble, allowing a walk and a single to the first two batters he faced. However, the righty reliever then induced a double-play groundout before striking out Brent Rooker to escape the jam. Zeferjahn has claimed a high-leverage role in a beleaguered Angels bullpen -- he's registered a hold in five straight outings to move into the team lead with eight this season. His 4.50 ERA and 1.50 WHIP on the campaign aren't great, but he has 26 punchouts (along with 10 walks) in 18 frames while adding two wins and a save.
