Chisholm (groin) went 1-for-3 with a walk and a run in Saturday's 4-3 loss to the Red Sox.

Chisholm re-entered the lineup Saturday after sitting out two games due to groin tightness. The veteran slugger seemed fine when he advanced from second to third base on a flyout in the second inning and when he scored from second base on a single in the seventh, so the injury appears to be behind him. Chisholm has posted a .998 OPS with two home runs, seven RBI and four steals over nine games since returning June 3 from a stint on the injured list.

Muncy went 1-for-4 with a two-run home run in Saturday's win over Kansas City.

The infielder launched a hanging slider from Michael Lorenzen into the left-field bullpen for a two-run homer in the second inning. Muncy has shown a clear uptick in power since being called back up in early June, slashing .270/.289/.595 with four home runs and 11 RBI over 37 at-bats. This may be a lost season for the Athletics in terms of playoff contention, but continued growth from the rookie would be a welcome development.

Schneemann went 2-for-3 with a walk, a stolen base and one run scored in Saturday's 4-3 loss to the Mariners.

Schneemann spent a large portion of the week on the bench due to a run of opposing left-handed pitchers, but he's been back in the lineup at second base against a pair of Seattle right-handers. The infielder has gone 7-for-24 (.292) over seven contests in June, logging three steals and two RBI in that span. For the season, he's at a .248/.333/.436 slash line with five steals, seven home runs, 18 RBI, 21 runs scored and seven doubles over 169 plate appearances while primarily serving in a strong-side platoon role.

Chisholm (groin) will start at third base and bat fifth against the Red Sox on Saturday.

Chisholm sat out back-to-back contests after injuring his groin Wednesday, but a few days of rest has him feeling well enough to return to the starting nine. The 27-year-old infielder has been great since the start of June, going 9-for-26 (.346) with two homers and seven RBI in his last eight games.

The Astros selected Guillorme's contract from Triple-A Sugar Land on Saturday, Brian McTaggart of MLB.com reports.

Guillorme had spent the campaign with Sugar Land until Saturday, posting a .248/.377/.317 slash line with two homers, 22 RBI and three stolen bases over 57 contests. The veteran utility man logged big-league time with three different teams last year after spending the first six years of his MLB career with the Mets. Guillorme's call-up was part of a flurry of Astros roster moves Saturday -- pitcher Spencer Arrighetti (thumb) was transferred to the 60-day IL, outfielder Jacob Melton (ankle) landed on the 10-day IL, utility man Shay Whitcomb was optioned to the minors and outfielder Cooper Hummel also had his contract selected from Triple-A.

Houston optioned Whitcomb to Triple-A Sugar Land on Saturday, Brian McTaggart of MLB.com reports.

Whitcomb had been summoned to the big club May 31 and went 0-for-7 with three strikeouts and no walks while up in the majors. He'll now return to Sugar Land, where he was a .956 OPS with 18 homers, 38 RBI and six steals over 53 games this season. Whitcomb's demotion was part of a series of Astros roster moves Saturday -- Jacob Melton (ankle) landed on the 10-day injured list, both Cooper Hummel and Luis Guillorme were selected from Triple-A and Spencer Arrighetti (thumb) was transferred to the 60-day IL.

Schneemann started at second base and went 0-for-4 in Friday's 7-2 loss to Seattle.

Schneemann made his first start in five games, and Friday marked the first time in five games that the Guardians faced a right-hander. He's doing better against righties (.802 OPS) than southpaws (.526), so he should continue to serve on the strong side of a platoon, though Schneemann has recently struggled, going 14-for-72 (.194) over his last 23 contests.

Lowe went 3-for-4 with a walk and a run scored Friday against the Mets.

Lowe has had hits come in bunches in June, as Friday marked his third multi-hit game across 11 starts in the month. He began the Rays' rally in the sixth inning with a single and came around to score, giving him eight runs scored in that same 11-game span.

Castro went 1-for-4 with a solo home run in Friday's 10-3 loss to the Astros.

All three Twins runs came on solo shots, with Castro getting his team on the board by taking Colton Gordon deep in the fourth inning. Castro has been on fire since the end of May, slashing .408/.491/.796 over his last 14 games with five homers, 10 RBI and 12 runs, and with Royce Lewis (hamstring) suffering another injury Friday, the 28-year-old utility player will have a little less competition for playing time in the immediate future.

Torres went 2-for-4 with two home runs and three RBI in Friday's 11-5 win over the Reds.

Torres opened the scoring with a leadoff homer in the first inning and went deep again in the seventh. It was a much-needed power surge for the 28-year-old, who hadn't homered since May 12 and entered Friday with just one extra-base hit over 12 June games. On the season, he's slashing .271/.373/.414 with seven home runs, 33 RBI, 32 runs scored and four steals across 249 plate appearances.
