The Orioles placed Mountcastle on the 10-day injured list Saturday with a right hamstring strain.

Mountcastle had to make an early exit from Friday's contest due to a hamstring issue, and imaging later revealed a strain. While the 28-year-old is out, Coby Mayo will come up from the minors to fill the open spot on the active roster.

Toro started at first base and went 3-for-4 with a double, an RBI and a run scored in Friday's 5-1 win over Atlanta.

First base has been chaotic since Triston Casas (knee) suffered a season-ending injury, but Toro has made a case for himself. He's gone 14-for-42 (.333) with three home runs, four doubles, five RBI and seven runs scored over the last 12 games. However, the Red Sox intend to experiment with Kristian Campbell at first base for at least one game during this weekend's series in Atlanta.

Guerrero went 1-for-3 with three walks, a run scored and an RBI in Friday's win over the A's.

Athletics pitchers issued 11 free passes in total on the night, while every Blue Jays hitter collected at least one hit, leading to an 11-7 victory. Guerrero has reached base safely in an impressive 30 straight games, slashing .288/.407/.468 over that span with six homers, 14 RBI and 23 runs.

Mountcastle was removed from Friday's game against the White Sox due to right hamstring discomfort, Andy Kostka of TheBaltimoreBanner.com reports.

Mountcastle went 2-for-3 with a steal and a run scored prior to being replaced in the eighth inning, with Cooper Hummel entering in right field while Ryan O'Hearn shifted over to first base. Mountcastle will undergo further tests and the Orioles should provide an update on his injury during or shortly after Friday's contest.

Walker (hand) is starting at first base and hitting cleanup Friday against the Rays.

He exited Wednesday's game after getting hit on the hand by a pitch, but X-rays were negative and he just needed one day off before getting back in the mix. Walker is hitting .229 with three home runs in 25 games this month.

Guerrero went 1-for-4 with a two-run home run in Thursday's rout of the A's.

The majestic second-inning blast over the left-field fence came off Jacob Lopez, and while it only traveled 399 feet, the ball reached a height of 136 feet after leaving Guerrero's bat with an eye-popping launch angle of 37 degrees. It was Guerrero's eighth homer of the year and his fourth in the last 14 games -- a stretch in which he's slashing .240/.367/.480 with six RBI, nine runs and a 9:4 BB:K.

Walker (hand) isn't in the lineup for Thursday's game against the Rays.

Walker had to make an early departure from Wednesday's contest after taking a pitch off his right hand. X-rays came back negative after the game, but the team will give him a day to recover from any lingering soreness that might still be bothering him. As a result, Victor Caratini will fill in at first base Thursday and bat fourth.

Alexander isn't in the lineup for Thursday's game versus Toronto.

After making back-to-back starts at first base in the absence of Nick Kurtz (hip) and going 0-for-6 with three strikeouts, Alexander will grab a seat on the bench Thursday. His absence will put Logan Davidson at first base and ninth in the Athletics' batting order.

X-rays on Walker's right hand came back negative after he was hit by a pitch during Wednesday's game against the Athletics, Brian McTaggart of MLB.com reports.

Walker remained in the game immediately after getting plunked in the fourth inning but was eventually replaced in the sixth. He appears to have escaped the incident without suffering any significant damage, so while the Astros may give him a day or two off to recover, he shouldn't need to miss extended time.

Walker was removed from Wednesday's game against the A's after being hit by a pitch on his right hand, Chandler Rome of The Athletic reports.

The first baseman initially stayed in the game after being struck by a 96-mph fastball during the fourth inning, but he was replaced by a pinch hitter two frames later. The specifics of the injury remain unclear, and Walker will likely undergo medical imaging to determine the severity of the issue.
