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.

Rojas hit a solo home run in his lone at-bat in Saturday's 11-5 win over the Giants.

Rojas continues to primarily feature off the bench, giving him little opportunity to make an impact. He hasn't done much with those chances either, going 9-for-50 (.180) over 25 games since the start of May, though two of his hits in that span have been his two homers this year. The infielder is batting .223 with a .574 OPS, six RBI and nine runs scored over 99 plate appearances, and there's little chance he escapes a reserve role unless injuries arise.

Gorman went 1-for-3 with a three-run home run, two walks and an additional run scored in Saturday's 8-5 win over the Brewers.

Gorman crushed a 433-foot homer off Jose Quintana to give the Cardinals a 7-1 lead in the fifth inning. He has been swinging a hot bat in June, going 9-for-28 with three home runs, eight RBI and five runs scored over 11 games. The 25-year-old is slashing .220/.317/.398 with four long balls, 17 RBI and 17 runs scored across just 139 plate appearances this season. He could be at risk of returning to the bench with Brendan Donovan (toe) expected back Sunday but has certainly made a strong case for continued playing time with his recent performance.

Donovan (toe) expects to return to the lineup Sunday versus the Brewers, John Denton of MLB.com reports.

Donovan took batting practice and fielded ground balls Saturday and was pain-free afterward. He will wear a carbon-fiber orthotic in his shoe in the short term, but it appears that he will avoid a stint on the injured list after missing the past four games.

Edman isn't in the lineup for Saturday's game against the Giants.

Edman will get a day to rest after going 0-for-3 during a loss in Friday's series opener. Hyeseong Kim will fill in at the keystone and bat ninth.

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.

Donovan (toe) isn't in the lineup for Saturday's game against the Brewers.

Saturday marks Donovan's fourth consecutive absence from the starting lineup due to a sprained big toe on his left foot. The Cards are expected to decide Sunday whether he needs to spend time on the injured list, and until he returns, Nolan Gorman will continue to start at second base.

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.
