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.

Fitts did not factor into the decision in Sunday's loss to the White Sox, allowing two runs (zero earned) on six hits and one walk while striking out two in 5.2 innings.

Fitts pitched well in his MLB debut, cruising through five scoreless innings before allowing two unearned runs in a rocky sixth inning that included a Triston Casas error. Fitts used just 66 pitches in 5.2 innings, pitching to contact against an inept White Sox offense. Fitts struck out only two batters Sunday, but he has shown adequate strikeout potential in the minor leagues -- in 24 starts for AAA-Worcester this season, Fitts compiled a 4.17 ERA, 1.27 WHIP and 111:37 K:BB in 116.2 innings. If Fitts sticks around in the rotation, he will face a much stiffer test next weekend against the Yankees.

Uceta notched his second save of the season Sunday against Baltimore, allowing one hit and one walk while striking out four in 1.2 innings.

Called upon to preserve a 2-0 lead with two runners on and one out in the eighth, Uceta promptly struck out the next two batters to escape the jam. Uceta then worked around a single and a walk in the ninth to pick up his second save of the season. Save opportunities have been few and far between, but Uceta has been dominant since Pete Fairbanks (lat) landed on the injured list on Aug. 19, throwing 7.1 scoreless innings with a sparkling 15:2 K:BB during that stretch. The 26-year-old Uceta hasn't allowed a run since July 31 and owns an impressive 0.75 ERA, 0.69 WHIP and 50:6 K:BB in 36 innings this season.

Double-A Corpus Christi placed Santa on its 7-day injured list Aug. 30 with an unspecified injury.

The 21-year-old righty made 14 starts for Single-A Fayetteville in 2023, but he's made the full-time move to the bullpen in 2024. Before landing on Corpus Christi's IL, Santa had produced an 8.69 ERA, 2.14 WHIP and 16:16 K:BB in 19.2 innings for the Double-A club.
