The Orioles selected Mayo's contract from Triple-A Norfolk on Friday.

The 22-year-old is joining Baltimore for his first look in the big leagues after Jordan Westburg suffered a fractured right hand Wednesday. Mayo will make his MLB debut Friday in Cleveland, starting at third base and batting eighth. He's one of the top prospects in baseball and has a .301/.375/.586 slash line with 20 homers in 77 games at Triple-A this season.

The Athletics optioned Harris to Triple-A Las Vegas on Thursday.

Harris had been hitless across his last six contests. With Harris back in the minors, Abraham Toro should return to being the Athletics' everyday third baseman.

Garcia went 1-for-5 with a run and two stolen bases in a 7-1 win against the Tigers on Thursday.

Garcia made the most of his lone trip on the basepaths, following his first-inning single with a pair of thefts before coming home to score. The infielder is up to 27 stolen bases on the campaign, sixth-most in the majors. Garcia is batting just .237 this season, but he's been much better than that for nearly a month, hitting .302 over 63 at-bats since July 7.

Ramirez went 2-for-3 with a home run, a double, two total runs and three total RBI in Thursday's 10-3 win against the Orioles.

Ramirez recorded an RBI in the first inning with a sacrifice fly. The third baseman added a two-run homer in the seventh frame before being lifted for a pinch hitter in the eighth with the Guardians holding a big lead. Ramirez has gone deep at least once in each of his past three contests, tallying four long balls, two doubles, six runs and eight RBI over that span.

Rengifo (wrist) isn't in the Angels' lineup Thursday against the Rockies, Jeff Fletcher of The Orange County Register reports.

Rengifo made an early exit from Wednesday's game after injuring his wrist on a swing. He's reportedly feeling better ahead of Thursday's contest, but he will step out of the lineup for a day as a precaution. In his absence, Brandon Drury will shift to third base while Michael Stefanic starts at the keystone and bats second.

DeJong isn't in the Royals' lineup for Thursday's game against the Tigers.

DeJong went 1-for-3 with a walk and a run score during his Royals debut Wednesday, and he'll now take a seat for Thursday's series opener. Maikel Garcia will slide to third base while Michael Massey starts at second, opening up the DH spot for Freddy Fermin.

The Orioles placed Westburg on the 10-day injured list Thursday with a right hand fracture.

Westburg suffered the unfortunate injury when he was hit by a pitch in Wednesday's win over the Blue Jays. The Orioles haven't provided a timetable for Westburg's return to action, but he could be sidelined well into September. Baltimore is set to use Jackson Holliday at second base and Ramon Urias at third base most days, but prospect Coby Mayo could eventually get called up from Triple-A Norfolk and receive a look at the hot corner.

Devers went 3-for-5 with two doubles and an RBI in Wednesday's 3-2 extra-inning win over the Mariners.

Devers walked off Seattle with a double in the top of 10th inning that plated Tyler O'Neill. The three-hit performance extended a hit streak to eight games, during which Devers has gone 17-for-32 (.531) with 10 extra-base hits, seven RBI and seven runs scored.

Rojas went 2-for-5 with a solo home run in Wednesday's extra-inning loss to the Red Sox.

Rojas gave Seattle its first and only lead in the fifth inning with a solo shot to center field. It was just his second homer during a rough July in which the third baseman batted .200 over 70 at-bats, though he did work 13 walks. Rojas batted leadoff for the first time in six games Wednesday, and that could continue to be his slot in the lineup for as long as Victor Robles (hip) remains out of action.

Rengifo was removed from Wednesday's game against the Rockies due to a flareup of his right wrist injury, Jeff Fletcher of The Orange County Register reports.

Rengifo was having problems with his wrist after a swing in the eighth inning of Wednesday's contest. No plans are in place to take him in for imaging, though that could change if his wrist is still bothering him ahead of Thursday's series finale. The 27-year-old was forced to sit out for nearly three weeks after he first injured his wrist July 3.
