Manager Matt Quatraro said Monday that he expects Schreiber (knee) to begin his rehab assignment Wednesday, Anne Rogers of MLB.com reports.

Schreiber landed on the 15-day IL on July 29 due to a right knee patella tendon injury. He threw his second bullpen session Sunday, and the 30-year-old right-hander is ready to embark on a rehab assignment to prepare himself for a return to the big club. Across 43 major-league outings this season, Schreiber has registered one save and 20 holds with a 4.14 ERA and 1.41 WHIP across 37 innings.

The Red Sox recalled Horn from Triple-A Worcester on Monday, Jen McCaffrey of The Athletic reports.

Horn holds a 6.39 ERA over nine relief appearances during his time with Boston this season. He'll give manager Alex Cora a fresh bullpen arm.

The Red Sox optioned Keller to Triple-A Worcester on Monday, Jen McCaffrey of The Athletic reports.

Keller made one extended relief appearance during his most recent stint in the majors, allowing three runs over four frames and taking a loss against the Astros on Saturday. He will likely re-enter Worcester's rotation.

Holmes earned a save against the Rangers on Sunday, allowing one run on one hit and two walks while striking out two batters over 1.1 innings.

New York carried an 8-3 lead into the eighth frame before reliever Mark Leiter surrendered three runs on three hits and allowed the tying run to come to the plate in the form of Corey Seager. Holmes entered at that point and got Seager to ground out to squelch the threat, and the closer then began the ninth with two straight punchouts. However, he almost let things get away from him, as Holmes proceeded to issue two straight walks followed by an Adolis Garcia RBI single. Texas' rally ended up falling just short when the next batter, Leody Taveras, grounded out. Holmes thus established a new career high with 25 saves, though he's also blown a career-worst nine saves on the season.

Taylor fired a scoreless ninth inning in a win over the Mets on Sunday, allowing a walk and recording two strikeouts.

The precocious rookie was impressive in his big-league debut, which came after a promotion straight from Double-A Arkansas. Taylor wrapped up his first frame in the majors in signature fashion, recording swinging strikeouts of Luis Torrens and Tyrone Taylor to close out Seattle's 11-run victory. Taylor's above-average ability to miss bats earned him plenty of high-leverage work at Arkansas thus far this minor-league season, but his initial assignments in the majors will likely continue to be of the low-leverage variety.

The Twins reinstated Okert (personal) from the bereavement list Monday.

Right-hander Randy Dobnak was optioned to Triple-A St. Paul to open up a spot on the 26-man active roster for Okert, who was away from the team for the past week while tending to the personal matter. Okert has mostly operated as a middle-relief arm for the Twins this season, logging a 4.45 ERA and 1.48 WHIP to go with three wins, one save and six holds over 30.1 innings.

The Twins optioned Dobnak to Triple-A St. Paul on Monday.

Dobnak wasn't going to be available for at least a day or two after throwing three scoreless relief innings in Sunday's loss to the Guardians. He'll cede his spot on the 26-man active roster to left-hander Steven Okert (personal), who was reinstated from the bereavement list.

Blue Jays manager John Schneider said Friday that Romano (elbow) is "progressing well" and is "feeling good" following his July 3 arthroscopic surgery, but the right-hander has yet to restart a throwing program, MLB.com reports.

After being placed on the injured list June 1 due to a right elbow inflammation, Romano twice had his throwing program shut down before he eventually required a procedure to repair an impingement. Though the Blue Jays seem satisfied with Romano's condition five weeks after surgery, he likely won't be rushed back into action, especially with Toronto out of playoff contention. Romano hasn't been ruled out from pitching again this season, but once he starts throwing again, the Blue Jays will have to wait and see how the 31-year-old's elbow responds before mapping out a potential target date for his return from the IL.

Waguespack (shoulder/back) is hopeful to resume throwing bullpen sessions by Tuesday, MLB.com reports.

Initially placed on the injured list May 6 with right rotator cuff inflammation, Waguespack was cleared to make a rehab start in the rookie-level Florida Complex League on June 25, only to fall victim to a lower-back issue that has kept him from pitching in a game ever since. He received injections Aug. 5 to address the back issue, and assuming the shots had the desired effect, Waguespack will take the next step forward in his throwing program by getting back on the mound this week. Even though the Rays likely envision Waguespack serving as a multi-inning reliever rather than a starter when he returns from the IL, he'll still likely need multiple weeks to complete a throwing progression and minor-league rehab assignment.

Fairbanks picked up the save Sunday against Baltimore, allowing one hit and no walks with three strikeouts across a scoreless ninth inning.

Fairbanks pounded the strike zone, as 12 of his 14 pitches were strikes. The 30-year-old has racked up eight consecutive scoreless innings, with two hits and no walks allowed during that stretch. He's 23-for-25 in save opportunities this season and has a 2.74 ERA and 1.08 WHIP across 42.2 innings.
