Brieske will serve as the Tigers' opening pitcher for Monday's game against the Guardians, Chris McCosky of The Detroit News reports.

Jack Flaherty had been scheduled to start Monday, but the Tigers opted to scratch him so as not to risk exposing him to an injury that might jeopardize a trade prior to Tuesday's deadline. The Tigers will thus turn to Brieske to make his second start of the season, though like on the previous occasion he started July 14 against the Dodgers, he probably won't be counted on to cover more than an inning or two. Bryan Sammons was called up from Triple-A Toledo on Monday and could operate as a bulk reliever behind Brieske.

The Tigers optioned Lucas to Triple-A Toledo on Monday.

Lucas was a waiver pickup by the Tigers earlier this season and has permitted two runs over 3.1 innings during his brief time in Detroit. Bryan Sammons was called up from Triple-A to take Lucas' spot on the 26-man active roster.

Garcia earned a save against Oakland on Sunday, retiring all three batters he faced in the ninth inning.

Angels manager Ron Washington said before the game Sunday that Garcia would step into the closer role after Carlos Estevez was traded to Philadelphia on Saturday, and the skipper held true to this word when he brought Garcia into the contest with Los Angeles up by two runs in the top of the ninth inning. The veteran reliever did his part to reward his manager's confidence, needing just nine pitches to set the side down in order. The save was Garcia's career-high fourth of the campaign, and he's added 12 holds along with a 3.71 ERA, 1.17 WHIP and 40:14 K:BB over 43.2 frames overall.

Garcia recorded his 12th hold in a win over the White Sox on Sunday, firing a perfect eighth inning.

Garcia was just acquired via trade with the Blue Jays on Friday, and he's been put right to work with the Mariners. Sunday's stellar seven-pitch outing was preceded by Garcia's Saturday debut, when he earned his 11th hold with a pair of strikeouts over one clear inning. Garcia figures to see plenty of seventh- and eighth-inning work now that Ryne Stanek has been traded to the Mets, and he should also be in line for an occasional save opportunity on days Andres Munoz is unavailable.

Bido (2-2) took the loss against the Angels on Sunday, allowing seven earned runs on six hits, four walks and a hit batsman over 3.2 innings. He struck out six.

Bido's swing-and-miss numbers weren't bad, but he otherwise had a rough go of it against what had been a light-hitting Angels squad. He actually cruised through his first two frames, but his unraveling began in a third inning during which the Angels sliced a 6-0 deficit in half via a Luis Rengifo RBI groundout and Willie Calhoun two-run single. Bido then issued three walks and a go-ahead grand slam to Taylor Ward in the fourth, putting the right-hander on the hook for the eventual loss. The 28-year-old saw his ERA shoot up from 3.09 to 5.00 with the rocky outing, but Bido is likely to remain in the rotation for the time being and projects to draw an unenviable matchup in the Dodgers for his next start this coming weekend.

The Blue Jays recalled Eisert from Triple-A Buffalo on Monday.

Eisert will serve as Toronto's 27th man during Monday's doubleheader in Baltimore and will be available out of the bullpen for both games. The left-hander has made one relief appearance for the Blue Jays this season, tossing two scoreless frames. He'll likely be sent back down to Buffalo following the twin bill.

Royals general manager J.J. Picollo said Monday that Schreiber (knee) is likely to be placed on the 15-day injured list, Joel Goldberg of Bally Sports Kansas City reports.

The Royals haven't provided an updated diagnosis for Schreiber after he was forced out of his relief appearance in Sunday's 7-3 loss to the Cubs with right knee patella tendon discomfort, but the team has apparently already deduced that the right-handed reliever is dealing with more than a day-to-day concern. Schreiber could cede his spot on the Royals' 26-man active roster to right-hander Michael Lorenzen, whom Kansas City acquired from Texas earlier Monday.

The Tigers acquired Vanasco from the Dodgers on Monday in exchange for cash considerations and optioned him to Triple-A Toledo.

Vanasco will fill the spot on the Tigers' 40-man roster that opened up after Detroit traded catcher Carson Kelly to the Rangers on Sunday. The right-hander reached the big leagues for the first time earlier this season with the Dodgers, but he made just two appearances out of the bullpen before being optioned to Triple-A earlier this month and then designated for assignment. Vanasco owns a 3.47 ERA, 1.73 WHIP and 27:21 K:BB in 23.1 innings out of the bullpen at the Triple-A level this season.

Cleavinger (7-2) struck out one without allowing a baserunner in a scoreless eighth inning to earn the win Sunday against the Reds.

Cleavinger entered with the Rays down 1-0 in the eighth inning and turned in his fifth consecutive clean outing. He's also picked up two wins in that span and should be locked into a high-leverage relief role after the departure of Jason Adam.

The Rangers acquired Pennington from the Royals on Monday in exchange for right-hander Michael Lorenzen.

Pennington, 26, has made one scoreless appearance in the majors this season and boasts a 2.26 ERA and 79:20 K:BB across 59.2 innings at the Triple-A level in 2024. The left-hander will be assigned to Triple-A Round Rock for now but could contribute to the Rangers bullpen in the second half.
