Harris is scheduled to start Saturday's game against the Blue Jays in Oakland, Ben Nicholson-Smith of Sportsnet.ca reports.

The Athletics' decisions to designate Aaron Brooks for assignment over the weekend and to option Joe Boyle to Triple-A Las Vegas on Wednesday after activating him from the injured list had already suggested that Harris was on track to remain in the rotation. Harris previously made two long-relief appearances for Oakland this season before drawing a start in Tampa Bay last Thursday, when he struck out seven and allowed three runs (one earned) over 5.2 frames in a no-decision. The southpaw has turned in a 7.67 ERA and 1.79 WHIP over his eight starts at Las Vegas this season and produced a 7.14 ERA over 63 innings in the big leagues in 2023, so fantasy managers should tread carefully with Harris for now even after his solid showing in his last outing.

Joyce earned a hold by tossing a scoreless inning while allowing one hit against San Diego on Wednesday.

Joyce was called up from the minors Sunday and was deployed in a high-leverage situation in his first outing with the big club, getting the eighth inning with the Angels up one run. The fireballing reliever immediately got into trouble when Fernando Tatis led off the frame with a single and advanced to second on a wild pitch, but Joyce calmed down to retire the next three batters without Tatis advancing further. Joyce didn't notch any strikeouts, but he had his heater working in the outing, reaching 103.3 mph, per Rhett Bollinger of MLB.com. The right-hander fanned 34 batters over 19 frames in the minors this season and could certainly be a big bullpen asset (and perhaps a future closer) in the majors if he learns to harness his control. In 10 innings with the Angels as a rookie last season, Joyce fanned 10 batters but also issued nine free passes.

Munoz (back) played catch prior to Thursday's game in Oakland, Shannon Drayer of Seattle Sports 710 AM reports.

Drayer adds that Munoz was seen giving fist bumps to others afterward, which would seem to indicate things went well. Munoz had to be removed from an appearance Thursday versus the Athletics, but there's optimism he can avoid the injured list and could be available to pitch this weekend in Kansas City, per Daniel Kramer of MLB.com.

The Red Sox activated Campbell (shoulder) from the 15-day injured list Thursday and optioned him to Triple-A Worcester, Christopher Smith of The Springfield Republican reports.

Campbell has been out for much of the season with a right shoulder impingement. He allowed just one unearned run with an 8:2 K:BB over 6.1 innings on his rehab assignment, but the Red Sox have elected to keep him at Worcester for the time being.

Munoz (back) said Wednesday that he's feeling better and remains optimistic he'll avoid a stint on the injured list, MLB.com reports.

The results of the right-hander's MRI are still pending, but Munoz appears confident the flareup of a lower-back issue that caused his removal from Tuesday's appearance is temporary. Munoz revealed Wednesday he had actually been dealing with his back strain since the second game of the season and has been managing it with treatment and other pain-management remedies. Consequently, the collision with the Athletics' Max Schuemann in Tuesday's game wasn't the actual culprit, as Munoz added that he had already been feeling back tightness when warming up in the bullpen that night. Munoz's MRI results could be the ultimate determining factor in whether he avoids an IL stint, with those results likely to be available at some point Thursday.

Santos (lat) threw a limited bullpen session before Tuesday's game against the Athletics, the Associated Press reports.

The right-hander remains without a timetable for his season debut, but Santos could be looking at a post-All-Star-break return considering he'll presumably need a fairly lengthy rehab assignment. Santos was a versatile relief asset for the White Sox last season while recording two wins, six holds and five saves, and once healthy, he could eventually prove to be a viable sixth- or seventh-inning option in his new Seattle digs.

Garcia (2-0) picked up the win Wednesday over the Orioles, striking out two in a perfect ninth inning.

The right-hander needed only 10 pitches (eight strikes) to dispatch Baltimore's 6-7-8 hitters in the ninth, and Garcia got rewarded when Isiah Kiner-Falefa hit a walk-off single in the bottom of the frame. Garcia has recorded a win (one), save (one) or hold (five) in seven of 10 appearances over the last month, posting a 2.53 ERA, 0.94 WHIP and 15:4 K:BB in 10.2 innings during that stretch. He'll continue to serve as the Blue Jays' primary closer until Jordan Romano (elbow) returns from the injured list.

The Orioles optioned Vespi to Triple-A Norfolk on Thursday.

Vespi's latest stint with the big club lasted just three days, with the lefty reliever tossing a scoreless inning during his lone appearance Tuesday versus the Blue Jays. He'll cede his spot on the 26-man active roster to left-hander Cade Povich, who was called up from Norfolk to start Thursday's series finale in Toronto.

Kimbrel (4-2) allowed an unearned run on two hits over one-third of an inning, taking the loss Wednesday versus the Blue Jays.

Isiah Kiner-Falefa delivered a walk-off single in the ninth inning to hand Kimbrel his first loss since April 28. This also ended Kimbrel's scoreless streak at 7.2 innings, though he hasn't given up an earned run since May 8. The closer has a 2.95 ERA, 1.03 WHIP, 31:9 K:BB and 13 saves in 16 chances through 21.1 innings this season.

Urena (2-5) earned the win over Detroit on Wednesday, allowing one run on one hit and one walk while striking out six batters over 6.2 innings.

Urena got through five perfect frames until Tigers rookie Justyn-Henry Malloy tagged him for his first MLB homer leading off the sixth inning. Urena rebounded by retiring the next five batters before getting pulled following a two-out walk in the seventh. The veteran righty's 6.2 frames tied a season-high mark and were enough to give him his third quality start over his past five appearances. Despite Urena's strong outing, he may be pushed out of the rotation this weekend if Jon Gray (groin) is ready to return from the injured list.
