Andujar isn't in the lineup for Thursday's game against the Astros.

Andujar will grab a seat on the bench Thursday after going 2-for-10 with four strikeouts during the Athletics' three-game set against the Rangers. While he rests, Gio Urshela will pick up a start at third base, and Carlos Cortes will cover right field.

Guillorme (hamstring) went 0-for-3 with Triple-A Sugar Land in rehab game Wednesday.

Guillorme has been sidelined with a hamstring strain since early July but will presumably be able to return in a few days. What his role upon activation will be is unclear, however, as he managed only three hits across 20 at-bats prior to suffering the injury.

Caminero went 2-for-4 with a home run and three total RBI in Wednesday's loss to the White Sox.

Caminero contributed to an early Tampa Bay lead with a two-run blast in the first inning. He tacked on an RBI on a fielder's choice in the eighth frame, but the Rays ended up falling short. Caminero is in the midst of a seven-game hitting streak, during which he's batting .393 (11-for-28) with three homers and eight RBI.

Mayer said he will receive an MRI on his right wrist Thursday, Tim Healey of The Boston Globe reports.

Mayer exited Wednesday's contest in the fifth inning with wrist discomfort, and he was seen wearing a brace after the game. He said he is still in a bit of pain, but the team won't know more about the severity of his injury until he goes in for imaging. If the 22-year-old ends up needing to miss any amount of time, Romy Gonzalez would likely benefit from an uptick in starts.

Lewis went 2-for-2 with a solo home run, a walk and a double in Wednesday's 4-3 loss to the Dodgers.

It was Lewis' fifth homer of the season and his third in the month of July. The slugging third baseman is finally beginning to come around amidst what's been another injury-plagued campaign, and his recent surge could help him work his way back up Minnesota's batting order. Since the start of June, Lewis is slashing .322/.381/.529 with four big flies, six doubles and 16 RBI over 97 plate appearances.

Mayer was removed from Wednesday's game against the Phillies due to right wrist discomfort, Chris Cotillo of MassLive.com reports.

Mayer went 0-for-1 with a walk and a run scored before his wrist forced him out of the game in the fifth inning. The severity of his injury is unclear, but a day off for the Red Sox on Thursday will give him extra time to recover and possibly allow him to be ready for Friday's series opener against the Dodgers.

Shaw went 1-for-4 with a solo home run in Wednesday's 8-4 loss to the Royals.

The rookie took Steven Cruz deep in the seventh inning, Shaw's fifth homer of the season and third in the last five games. He's batting .474 (9-for-19) since the All-Star break, adding two steals, four runs and six RBI to his long balls, but he still has a lot of work to do to climb out of the hole he dug prior to the Midsummer Classic -- over his last 25 games before the break, Shaw slashed a woeful .107/.198/.147.

Bregman is out of the lineup for Wednesday's game against the Phillies, Tim Healey of The Boston Globe reports.

Bregman has acknowledged that he's still not quite 100 percent recovered from the quadriceps strain that kept him on the shelf from May 24 through July 11, so the Red Sox could give him one or two days off per week in an effort to keep him fresh. With Bregman getting a breather Wednesday, Marcelo Mayer will pick up the start at third base.

Chapman was lifted for a pinch hitter in the eighth inning of Wednesday's 9-3 win over Atlanta after he was hit by a pitch in the left elbow earlier in the contest, but X-rays returned negative, Justice delos Santos of The San Jose Mercury News reports. He went 1-for-2 with a two-run home run, a walk and an additional run prior to departing.

Chapman looked to be in pain when he was struck by an 89-mile-per-hour sinker in the top of the seventh, but he was able to stay in the game and then played an inning in the field before he was removed from the contest. The Giants held a six-run lead at the time of his departure, so Chapman may have just been pulled from the game as a precaution. With a team off day on tap Thursday, Chapman will have some extra time to heal before the Giants return to action Friday against the Mets.

Dodgers manager Dave Roberts said Wednesday that Muncy (knee) will travel to the team's spring training complex in Arizona on Thursday to take live at-bats for a few days, Sonja Chen of MLB.com reports.

If Muncy comes out of the workout without any hiccups, he could be cleared to begin a rehab assignment. The veteran third baseman has recovered from a left knee bone bruise more quickly than expected and is tracking toward a return from the 10-day injured list in early August if all continues to go well in his recovery process.
