The Rangers placed Martin on the 15-day injured list Monday with a left calf strain.

Martin suffered the injury during an appearance Sunday against the Tigers. He will be eligible for activation Aug. 5, but it's too soon to know whether he will have a chance to be ready to return on that date.

The Rangers recalled Winn from Triple-A Round Rock on Monday.

Winn has managed a 1.59 ERA in 17 relief innings with the big club this season, but a 11:8 K:BB suggests he's been fortunate. The right-hander will be used in low-leverage spots.

The Cubs optioned Roberts to Triple-A Iowa on Monday.

He's being replaced on the active roster by Ben Brown, who was recalled from Iowa. Roberts made one appearance for the Cubs after being called up earlier this month, allowing one run while recording two outs.

The Mariners selected Garcia's contract from Triple-A Tacoma on Monday.

Garcia has been used as a full-time reliever this season between Double-A Arkansas and Tacoma, producing a 3.51 ERA and 42:17 K:BB over 33.1 frames between the two stops. The lefty has the stuff to be a late-inning weapon for the Mariners in time, but he's likely to be used in low-leverage spots initially. Garcia will be making his major-league debut when he gets into a game.

The Mariners optioned Burgos to Triple-A Tacoma on Monday.

Burgos did a fine job in his first four major-league relief appearances, yielding three runs with an 8:2 K:BB over 6.2 innings. His spot on the 26-man active roster and in the bullpen is being absorbed by lefty Brandyn Garcia, who was called up from Tacoma.

Nittoli agreed to a minor-league contract with the Orioles on Monday, Roch Kubatko of MASNSports.com reports.

Nittoli opted out of his minor-league pact with the Brewers last week and has quickly landed in a new organization. The 34-year-old last appeared in the big leagues with the Orioles in 2024, making two scoreless appearances. Nittoli will report to Triple-A Norfolk.

The Blue Jays recalled Fluharty from Triple-A Buffalo on Monday.

Fluharty was sent down earlier this month following a rough stretch in which he surrendered 13 runs (12 earned) over his last 7.1 innings. The lefty seemed to right the ship at Buffalo, allowing one run with an 8:2 K:BB in 4.2 frames. Fluharty will give manager John Schneider a third southpaw in the bullpen ahead of a big series against the Yankees.

The Blue Jays optioned Pina to Triple-A Buffalo on Monday.

Pina had been with the big club for more than two weeks but made only one appearance during that time, allowing three runs (one earned) over 1.1 innings. Lefty Mason Fluharty was recalled from Triple-A to take Pina's spot in the bullpen.

Assad (oblique) will resume a rehab assignment with the rookie-level Arizona Complex League Cubs on Thursday, MLB.com reports.

Assad has been sidelined all season after aggravating a left oblique strain during a rehab start back in late April. The right-hander is hoping to be available for the Cubs at some point in August, but it's uncertain what his role would look like at that time.

The Mets transferred Nunez (elbow) from the 15-day injured list to the 60-day IL on Monday.

The transaction is merely procedural, as Nunez is slated to miss the rest of the season and likely the entire 2026 campaign after undergoing Tommy John surgery last Monday. The Mets claimed right-hander Rico Garcia from the Yankees on Monday and will have him take over Nunez's spot on the 40-man roster.
