The Mariners claimed Kitchen off waivers from the Marlins on Monday and optioned him to Triple-A Tacoma.

Seattle designated infielder Jason Vosler for assignment to clear room on the 40-man roster for Kitchen, a 27-year-old lefty reliever. He reached the big leagues for the first time this season but was lit up in his four appearances out of the Miami bullpen, giving up 11 earned runs on 16 hits and three walks over seven innings.

Alexander is expected to work in bulk relief behind opening pitcher Cole Sulser in Monday's game against the Phillies, Marc Topkin of the Tampa Bay Times reports.

Alexander is taking over the rotation spot vacated by lefty Jeffrey Springs (elbow), who landed on the injured list Sunday. Over his 19 appearances (seven starts) with Tampa Bay this season, Alexander sports a 6-4 record with a 5.66 ERA, 1.35 WHIP and 75:21 K:BB across 89 innings. He's been especially vulnerable to the long ball, giving up a career-high 22 home runs.

The Yankees designated Misiewicz for assignment Monday.

The transaction opens up a spot on the 40-man roster for utility man Jon Berti's (calf), who was activated from the 60-day injured list. Misiewicz made his lone appearance of the season with the Yankees back in June and had turned in a 3.47 ERA, 1.11 WHIP and 30:5 K:BB in 23.1 innings over 21 appearances since returning to Triple-A.

Booser (elbow) struck out a batter and gave up one hit in a scoreless inning in his rehab appearance Saturday with Double-A Portland.

Booser began his rehab assignment Aug. 29 with Triple-A Worcester, but he took a one-week break before making his return to game action this weekend, albeit at a different affiliate. The left-hander looked sharp Saturday and may require just one or two more appearances in the minors before returning from the 15-day injured list.

Burr will serve as the Blue Jays' opening pitcher in Monday's game versus the Mets, Ben Nicholson-Smith of Sportsnet.ca reports.

Ryan Yarbrough will be a candidate to eat up most of the innings Monday as a bulk reliever. Burr had one previous opener assignment last month, allowing two hits and a walk but no runs over one-plus innings.

Thornton (4-3) got the win against the Cardinals on Sunday, firing two scoreless innings during which he allowed a hit and recorded two strikeouts.

Thornton played a pivotal role in the Mariners' pitching plans Sunday, providing two nearly perfect innings following an earlier-than-expected call from the bullpen due to Luis Castillo's exit as a result of a hamstring strain. Thornton threw 28 pitches over his two frames and produced his 10th scoreless appearance in his last 11 outings, lowering his ERA under 4.00 (3.99) in the process. Thornton's versatility has been leveraged frequently this season, as he's logged a career-high 64 appearances that have helped him to a career-best nine holds and his most wins since he was primarily a starter for the Blue Jays in his rookie 2019 campaign.

Shuster will be the White Sox's opening pitcher in Monday's game against the Guardians, Scott Merkin of MLB.com reports.

Shuster is stretched out to go multiple innings, if needed, but Nick Nastrini is a prime candidate to cover the bulk of the frames in the series opener. Shuster is opening a game for the third time this season after allowing two earned runs over 3.2 innings in the first two outings.

Green blew the save Sunday against Atlanta, allowing one earned run on two hits and zero walks in one inning. He did not record a strikeout.

Called upon in the ninth to protect a one-run lead, Green allowed back-to-back singles to open the inning before yielding a Matt Olson sacrifice fly to the tie game. Green managed to keep the score tied thanks to a timely double play, but the damage was already done. The 33-year-old has now blown saves in each of his last three appearances, allowing seven earned runs in 2.2 innings during that span. Even with that disastrous stretch, the veteran owns a respectable 2.85 ERA, 0.97 WHIP and 42:11 K:BB in 47.1 innings this season, converting 16 of 19 saves.

Bubic struck out one over a perfect inning to earn his sixth hold of the year in Sunday's 2-0 win over the Twins.

While he's allowed six runs on 13 hits over his last nine innings, Bubic has more frequently received high-leverage assignments. In that same span, he has five holds and a blown save while adding 11 strikeouts. The southpaw is now at a 3.80 ERA, 1.17 WHIP and 27:3 K:BB through 21.1 innings this year, working exclusively out of the bullpen following his return from Tommy John surgery in April of 2023. While he's seen more setup work, Bubic shouldn't be considered a threat to Lucas Erceg as the Royals' closer.

Erceg allowed a hit and struck out one in a scoreless inning while earning a save against the Twins on Sunday.

Erceg worked around a leadoff single by Christian Vazquez to close out the 2-0 win. After blowing two straight save chances and allowing seven runs over three appearances, Erceg has now converted three consecutive saves. He's now 11 for 16 in save opportunities with a 3.67 ERA over 54 innings. Of those 11 saves, eight have come since his Royals debut July 31.
