The Athletics activated Severino (oblique) from the 15-day injured list Monday.

Severino is set to rejoin the rotation Tuesday with a start in St. Louis after missing more than three weeks with an oblique strain. The veteran right-hander didn't make a rehab start, instead throwing a simulated game last week. It's unclear how many pitches Severino threw in that sim game, but he'll likely be under a workload restriction against the Cardinals.

The White Sox recalled Ramos from Triple-A Charlotte on Monday.

The 23-year-old third baseman got his first taste of the big leagues last season, appearing in 32 games with Chicago and slashing .202/.252/.333 with three home runs, 11 RBI, 13 runs scored and a 7:22 BB:K across 108 plate appearances. He's spent the entire 2025 season at Triple-A, producing a .218/.317/.391 slash line with 14 home runs and 13 stolen bases over 392 trips to the plate. Ramos is unlikely to be in line for regular playing time with the White Sox in September, at least not right away.

The White Sox recalled Ellard from Triple-A Charlotte on Monday.

Per Jack Ankony of SI.com, Ellard will serve as the White Sox's opening pitcher for Monday's contest in Minnesota, likely covering an inning or two before turning the game over to the bullpen. Ellard was part of the late-inning mix for the White Sox last season but has collected a 5.87 ERA and 11:6 K:BB over 7.2 innings at the big-league level in 2025 and also holds a 6.48 ERA with Charlotte. Even with the continued uncertainty in Chicago's bullpen, Ellard will likely be kept away from high-leverage situations.

Arias (hand) remains out of the lineup for Monday's game versus the Red Sox.

Arias will miss a third straight start due to the bruised right hand he suffered after being hit by a pitch Friday. Brayan Rocchio will shift over to shortstop and Daniel Schneemann will get the start at second base Monday.

The Blue Jays transferred Sandlin (elbow) from the 15-day injured list to the 60-day IL on Monday.

This move doesn't affect Sandlin's timeline for a return, as he had been on the shelf since July 8. His throwing program has been paused multiple times during his ramp-up from right elbow inflammation, and he recently got an anti-inflammatory injection. Sandlin is expected to resume throwing once the shot takes full effect.

The Blue Jays selected Tate's contract from Triple-A Buffalo on Monday.

Tate was up in the majors earlier this season, yielding three runs with a 7:6 K:BB over 5.1 innings. He'll operate in middle relief down the stretch.

Varsho (hand) will start in center field and bat fifth in Monday's game against the Reds.

Varsho will make his return to the lineup after he had been held out of the starting nine for the final two games of the Blue Jays' weekend series versus Milwaukee due to a bruised right hand. He ended up coming off the bench and played an inning of center field in Sunday's 8-4 win, and with his hand providing no apparent complications following that contest, Varsho was given the green light to start in Monday's series opener in Cincinnati.

The Twins recalled Keirsey from Triple-A St. Paul on Monday.

Keirsey will operate as a reserve at all three outfield spots down the stretch for the Twins. The 28-year-old has put up just a .324 OPS and 37.6 percent strikeout rate across 85 big-league plate appearances this season.

The Guardians recalled Kent from Triple-A Columbus on Sunday.

Kent will be up with the Guardians for the sixth time this season, though he made just four relief appearances over his previous five stints in the majors and gave up five earned runs across 7.1 innings. He'll likely see most of his usage in lower-leverage spots during the final month of the season.

The Guardians selected Valera's contract from Triple-A Columbus on Monday.

He will start at designated hitter and bat seventh for his big-league debut Monday in Fenway Park against righty Brayan Bello. Valera was a premium dynasty prospect five or six years ago, but injuries greatly affected his development, and then his hit tool stalled out in the upper levels. Still just 24, the lefty-hitting outfielder slashed .255/.346/.457 with three home runs and a 25.2 percent strikeout rate in 28 games at Triple-A this season after returning from 2024 patellar tendon surgery.
