Trivino (elbow) agreed in mid-September to extend his minor-league rehab assignment an additional 10 days, per MLB.com.

Trivino continues to work his way back from Tommy John surgery performed last May and a bout of right elbow inflammation that sprung up this April. Though he has a 4.91 ERA and 1.45 WHIP over 11 rehab appearances, the veteran reliever has pitched three consecutive scoreless outings during which he's posted a 3:3 K:BB over 3.2 innings. Yankees manager Aaron Boone said Sept. 14 that Trivino has been "building a lot of good momentum," and there's still a chance the right-hander could join the New York bullpen before the end of the season.

The Astros recalled Martinez from Triple-A Sugar Land on Saturday

With Tayler Scott (back) headed for the injured list, the Astros will call upon Martinez to fill the open spot in the bullpen. The 30-year-old righty has been solid in the majors this season, posting a 3.04 ERA and 1.21 WHIP through 50.1 innings. He'll most likely work in middle relief down the stretch.

The Astros placed Scott on the 15-day injured list Saturday due to a thoracic spine strain.

Scott has been uncharacteristically bad during September, logging a 6.35 ERA and 4:5 K:BB across 5.2 innings. However, the poor performance can be attributed at least in some part to the spine injury. Scott won't be eligible to return during the regular season, but he could return for the playoffs. Seth Martinez was recalled from Triple-A Sugar Land in a corresponding move.

Marte had successful right shoulder surgery in mid-September, Rhett Bollinger of MLB.com reports.

Marte's placement on the injured list Aug. 10 was due to a viral infection, and he was transferred to the 60-day IL on Aug. 30. The righty reliever reportedly "felt something in his shoulder" while trying to build up his arm strength, which resulted in the decision to shut down his throwing and have him undergo shoulder surgery, per MLB.com. It's unclear whether Marte will be ready to pitch when spring training comes around next year.

The Red Sox reinstated Garcia (elbow) from the 15-day injured list Saturday, Jen McCaffrey of The Athletic reports.

Garcia has been held out of action since late August due to inflammation in his right elbow, but he's now been cleared to return after throwing a scoreless inning during a rehab appearance in Triple-A on Tuesday. The 37-year-old reliever has allowed 13 earned runs in just 11.1 innings since joining the Red Sox, and he'll most likely work in middle relief during the final stretch. Cooper Criswell was optioned to Worcester in a corresponding move.

Sabrowski allowed two hits and a walk while striking out two over 2.1 scoreless innings to earn the save in Friday's 5-1 win over the Cardinals.

Sabrowski entered the game with the Guardians ahead 4-1 in the seventh inning and covered the rest of the game. He has made six appearances -- five longer than one inning -- since joining the major-league roster Aug. 28. He's yet to allow a run while posting a 0.90 WHIP and 13:3 K:BB over 10 innings, maintaining strong strikeouts numbers while getting his walk rate under better control after posting a 7.3 BB/9 over 37 innings at Triple-A this year. Sabrowski will continue to fill a multi-inning role in the Guardians' elite bullpen.

The Twins optioned Henriquez to Triple-A St. Paul on Saturday.

After coming up from the minors in mid-August, Henriquez turned in a 3.94 ERA and 1.38 WHIP across 16 innings. After pitching in three of Minnesota's last four games, he'll be sent out to the minors in favor of Brent Headrick, who will provide a fresh arm in middle relief.

The Twins recalled Headrick from Triple-A St. Paul on Saturday.

Through 18 innings at Triple-A, Headrick owns a 2.00 ERA and 1.11 WHIP alongside a 23:6 K:BB. He'll be called upon to give the Twins a fresh bullpen arm while presumably serving in middle relief, replacing Ronny Henriquez.

Alexander didn't factor into the decision Friday against Toronto, allowing two hits and a walk over 4.1 shutout innings. He struck out six.

Alexander was sharp Friday, holding Toronto to just two singles, though he'd fail to qualify for the win as the Rays turned to the bullpen in the fifth inning after Alexander hit 65 pitches. Still, it was an encouraging performance from the left-hander, who had allowed 20 earned runs and eight homers in his previous six outings (27.1 innings). Overall, Alexander is 6-5 with a 5.35 ERA, 1.27 WHIP and 84:24 K:BB over 102.2 innings this year. He's lined up to face the Tigers on the road next week in what will likely be his final start of the season.

Hader struck out two in a perfect ninth inning Friday to record his 33rd save of the season in a 9-7 win over the Angels.

The Houston closer has been dominant to close out the regular season, striking out multiple batters in eight of his last 15 appearances while posting a 1.69 ERA, 0.56 WHIP and 22:4 K:BB through 16 innings over that stretch. Hader has reached triple-digit strikeouts on the season for the fourth time in his career, and he's produced at least 33 saves in four straight campaigns.
