The Tigers recalled Guenther from Triple-A Toledo on Friday, Evan Woodbery of MLive.com reports.

He's absorbing the roster spot vacated by Bailey Horn, who was optioned to Toledo on Thursday. Guenther got a late start to the season due to lumbar spine inflammation, but he's being summoned after allowing three runs over his first 3.1 innings in the minors.

Fairbanks earned the save in Thursday's 7-4 extra-inning win over the Diamondbacks after allowing one walk in a scoreless 10th inning. He struck out one.

It didn't appear initially that Fairbanks would be in action Thursday, but the Rays scored a run in the ninth inning to force extras and plated three more in the 10th to create a save opportunity for the closer. Even though the hard-throwing right-hander has a concerning 1.50 WHIP and 9:6 K:BB over 9.1 innings, he's converted each of his first four save chances and has a 2.89 ERA. Fairbanks' control issues could eventually come back to haunt him, but he has some decent stability as Tampa Bay's No. 1 option for saves coming off back-to-back 20-save campaigns.

Jackson (0-2) was charged with the loss and a blown save in Thursday's 4-3 loss to the Athletics, giving up two runs (one earned) on two hits and one walk in one inning. He struck out one.

Jackson entered the game with a runner on base in the eighth inning and put out Brent Rooker to protect a 3-2 lead, but trouble arose in the ninth frame. The first of his two runs allowed was unearned due to a Leody Taveras fielding error, but Jacob Wilson's walk-off single saddled Jackson with his first blown save of the year. The veteran right-hander has still converted seven of his eight save chances to go with a respectable 3.60 ERA, 1.20 WHIP and 7:3 K:BB over 10 frames, so he figures to remain the favorite for ninth-inning work in Texas' bullpen for the time being, despite Thursday's showing.

Horn was optioned to Triple-A Toledo on Thursday.

Horn was recalled to the majors Saturday and appeared in a game Tuesday, completing 1.1 innings while striking out two. He will likely have the chance to contribute out of the big-league bullpen later in the campaign.

Jansen secured the save in Thursday's 4-3 win over Pittsburgh after allowing one hit in a scoreless ninth inning. He struck out one.

Jansen poured in 14 of his 18 pitches for strikes, and he got Oneil Cruz to line out to end the game while the possible tying run was on first base. The 37-year-old right-hander has looked very sharp in the early going, giving up just five hits and two walks with eight punchouts while converting each of his six save chances over eight shutout innings to open the campaign. With Ben Joyce (shoulder) also on the injured list, Jansen is being relied upon even more for high-leverage work.

Bautista collected the save in Wednesday's 2-1 win over the Nationals, allowing one hit while striking out a batter in a scoreless ninth inning. He did not issue a walk.

Bautista was brought in for the ninth inning to protect a one-run lead. He needed 19 pitches (12 strikes) to make it through the frame, highlighted by a four-pitch punchout of James Wood to open the ninth. Bautista has earned a save in three of his last four outings and has not yielded a run over his last five games.

Gilbert will serve as the White Sox's opening pitcher for Friday's game against the Athletics,Scott Merkin of MLB.com reports.

Gilbert will be making his first MLB start since the 2022 season Friday, likely covering the first 1-to-3 innings of the game before giving way to Sean Burke, who had previously been in line to start in the series opener in Sacramento. Over his six appearances out of the bullpen this season, Gilbert has covered 5.2 innings while allowing five earned runs on five hits and three walks.

Garabito was recalled from Triple-A Round Rock by the Rangers on Thursday, Shawn McFarland of The Dallas Morning News reports.

Garabito earned a roster spot out of spring training but was optioned to Round Rock on April 8. He'll return to the majors Thursday with Kumar Rocker (shoulder) sidelined and will likely pitch in long relief out of the bullpen.

Eisert collected the save in Thursday's 3-0 rain-shortened win over the Twins, allowing one hit and striking out one batter in a scoreless seventh inning. He did not issue a walk.

Eisert was brought in for the seventh inning and needed 14 pitches (eight strikes) to get through the frame, only giving up a double to Christian Vazquez. The game was delayed following the seventh inning due to rain and was called an hour later, giving Eisert the first save of his major-league career. He has a 4.76 ERA. 1.32 WHIP and 15:2 K:BB across 11.1 innings this season.

Estevez earned the save in a 7-4 over Colorado in the first game of Thursday's doubleheader, turning in a perfect ninth inning.

After allowing three runs in a blown save in his last appearance Tuesday, Estevez bounced back with a clean ninth inning Thursday to lock down his sixth save of the year. The 32-year-old Estevez sports a 3.00 ERA with a 1.17 WHIP and 10:9 K:BB through his first 12 innings this season.
