Lopez (shoulder) will continue his rehab assignment Tuesday with Triple-A St. Paul, Bobby Nightengale of The Minnesota Star Tribune reports.

The veteran right-hander allowed one earned run on four hits with two strikeouts and a walk over 1.2 innings during his first rehab outing last week, and he's expected to build up to about four innings or 65 pitches Tuesday. Lopez has been sidelined by the shoulder strain since early June and will likely require an additional start or two in the minors after Tuesday before returning from the 60-day injured list.

Mountcastle is absent from the lineup for Tuesday's game versus the Red Sox.

It's a routine day off for Mountcastle, who had started each of the previous seven contests. The Orioles are going with Coby Mayo at designated hitter and Samuel Basallo at first base Tuesday.

The Astros optioned Matthews to Triple-A Sugar Land on Tuesday, Brian McTaggart of MLB.com reports.

Matthews was recalled last week but did not make an appearance during this most recent stint in the majors. He's clearing out to make room on the active roster for the return of Yordan Alvarez (hand).

The Astros placed Rooney on the 15-day injured list Tuesday due to left elbow inflammation, Brian McTaggart of MLB.com reports.

He will be eligible to return Sept. 9, but given the nature of the injury, Rooney might need more time to make a full recovery. The lefty reliever has made one appearance for Houston this season, surrendering one run over 1.1 frames.

The Astros recalled Blubaugh from Triple-A Sugar Land on Tuesday, Brian McTaggart of MLB.com reports.

Blubaugh has made one start and two relief appearances for the Astros this season, yielding 11 runs (six earned) with a 15:3 K:BB over 13 innings. He will pitch out of the bullpen.

The Astros activated Alvarez (hand) from the 60-day injured list Tuesday, Brian McTaggart of MLB.com reports.

Alvarez wound up missing nearly four months of action with a small fracture in his right hand. He is starting in left field and batting cleanup in Tuesday's game against the Rockies. Alvarez slashed only .210/.306/.340in 29 games earlier this season before getting hurt.

Alvarez (thumb) will begin a rehab assignment Wednesday, Laura Albanese of Newsday reports.

Alvarez took batting practice on the field Tuesday and insisted afterward that he feels no pain in his right thumb despite being diagnosed with a UCL sprain. He will be eligible for activation from the 10-day injured list Thursday, but the Mets could wait until rosters expand Sept. 1 to return their starting catcher to the active roster.

The Mets will call up Tong from Triple-A Syracuse to make his MLB debut with a start Friday against the Marlins at Citi Field, Anthony DiComo of MLB.com reports.

Manager Carlos Mendoza confirmed that the Mets will move to a six-man rotation to accommodate the arrival of Tong, who was established himself as one of the top pitching prospects in baseball this season. The 22-year-old righty has followed up his breakout 2024 season with an even better showing in 2025, accruing a 1.43 ERA and 0.92 WHIP to go with a minor-league-best 179 strikeouts in 113.2 innings covering 22 starts between Double-A Binghamton and Syracuse. Tong isn't necessarily guaranteed any starts beyond his debut, but he will get the chance to state his case to remain in the Mets rotation moving forward.

Chourio (hamstring) will play seven innings in the outfield during his rehab game with Triple-A Nashville on Tuesday and could rejoin the Brewers as soon as this weekend's three-game series in Toronto, Adam McCalvy of MLB.com reports.

The 21-year-old was a bit tentative while running the bases during his rehab game Sunday, so Milwaukee has elected to continue the minor-league assignment for at least a few more days. If Chourio can further ramp up and play in a full game with no issues, he should have a chance to come off the injured list to face the Blue Jays.

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

Moran has permitted three runs with a 5:3 K:BB over four innings covering two relief outings for the Red Sox this season. He will give manager Alex Cora another lefty in the bullpen.
