The Astros are expected to select Guillorme's contract from Triple-A Sugar Land on Saturday, Chandler Rome of The Athletic reports.

With Isaac Paredes (hamstring) and Jacob Melton (ankle) both going down with injuries over the past couple of days, the Astros will turn to Guillorme to provide some bench depth. The 30-year-old infielder hasn't been particularly impressive in the minors this season, slashing .245/.376/.310 with 21 RBI and 24 runs scored across 242 plate appearances.

Walls is out of the lineup for Friday's game against the Mets.

Walls had started five consecutive games at shortstop but will yield to Jose Caballero at the position Friday for the second time in three games. Walls is 8-for-24 (.333) with six RBI and three runs scored in June.

Wilson (hamstring) is in the Athletics' starting lineup Friday and is batting second against the Royals.

Wilson missed the final two games of the Athletics' series against the Angels earlier this week and had the off day Thursday, so he's back in action after getting three days of rest due to a tight hamstring. Wilson is slashing .366/.402/.520 with eight home runs, 38 RBI, 36 runs scored and five stolen bases across 272 plate appearances this season.

Smith started at shortstop and went 2-for-5 with a walk, a solo home run and two additional runs scored in Thursday's 16-3 win over Minnesota.

Smith homered to lead off the game, setting up the Rangers to score 16 runs for the second time in the series. He has multiple hits in four straight contests and six in 10 games during the month of June, during which he's gone 15-for-42 (.357) with four doubles, two home runs, seven RBI, two steals and seven runs. The versatile Smith will be in the lineup whenever the Rangers face a right-hander, either to give Corey Seager a breather at shortstop as he did Thursday, or at first base in place of Jake Burger, who has been deployed at designated hitter four times in the last seven contests.

Pena went 2-for-4 with a run scored in Thursday's 4-3 victory over the White Sox.

Pena keeps piling up multi-hit games, with Thursday's showing being his 24th of the campaign already. Seven of those have come in the month of June, and over his last 17 contests and 70 at-bats, the speedy shortstop is hitting .414 with three homers, six doubles, eight RBI, 13 runs scored and eight stolen bases.

Montgomery will start at shortstop and bat second for Triple-A Charlotte in Wednesday's game against Durham after having not played since last Thursday due to a hand injury, Dylan Barnas of FutureSox.com reports.

Montgomery has had some unfortunate luck on the injury front lately, but he's been able to avoid extended absences. After getting hit on the knee by a pitch in a May 30 game, Montgomery missed a few days before returning to the lineup June 4, only to get hit on the hand by another pitch in his second game back in action. The shortstop prospect needed just under a week off to heal up from the hand injury, and he should be ready to handle an everyday role for Charlotte moving forward. He's slashing .197/.287/.382 with seven home runs and two stolen bases over 171 plate appearances on the season for the Triple-A club.

Meidroth is out of the lineup for Wednesday's game against the Astros.

Meidroth will get a chance to catch his breath after logging a hit in seven of his last nine games, during which he went 12-for-33 with four RBI and four runs scored. Vinny Capra will take his place at shortstop Wednesday and bat ninth.

Walls will start at shortstop and bat ninth in Wednesday's game against the Red Sox.

Walls appears to have taken back primary duties at shortstop away from Jose Caballero, who is on the bench against a righty for the second time in three contests and who has also made two of his previous three starts in the outfield. Meanwhile, Walls will be occupying shortstop for the sixth time in seven games, with his hot run at the plate giving Rays manager Kevin Cash some extra incentive to keep his bat in the lineup. Walls has opened June by going 7-for-20 with a home run, two doubles, two walks, a stolen base and six RBI in seven contests. His stint at the top of the depth chart could be brief however, with Ha-Seong Kim (shoulder) closing in on his activation from the injured list.

Caballero is out of the lineup for Wednesday's game against the Red Sox.

Caballero should continue to play regularly versus left-handed pitching, but he seems to have fallen back into a timeshare at shortstop with Taylor Walls when the Rays face right-handed pitching. Caballero will take a seat for the second time in the Rays' last three matchups versus righties to open up a spot in the lineup for Walls, who offers a better glove and has been hot at the plate lately (7-for-17 with a home run and two doubles over his last five games).

Wilson (hamstring) remains out of the lineup for Wednesday's game versus the Angels.

Wilson was a late scratch from Tuesday's lineup due to left hamstring tightness and will miss a second straight start. The Athletics are off Thursday, so Wilson will hope to re-enter the lineup Friday in Kansas City. Max Schuemann will again fill in at shortstop and bat ninth.
