X-rays on Mateo's left arm came back negative after he was removed from Tuesday's game versus Miami following a collision with Gunnar Henderson, Andy Kostka of TheBaltimoreBanner.com reports.

Manager Brandon Hyde said Mateo will need to undergo an MRI in order to have a good idea of what the 29-year-old is dealing with, but a clean X-ray is an encouraging sign. Until the results of Mateo's MRI come back, he should be viewed as day-to-day.

Mateo was removed from Tuesday's game against the Marlins due to a left arm injury, Andy Kostka of TheBaltimoreBanner.com reports.

Mateo collided with Gunnar Henderson after both players dove for a groundball in the third inning, causing Mateo's arm to bend awkwardly. Mateo was immediately taken out of the game and replaced by Ramon Urias, and the Orioles' training staff will presumably take him in for imaging to determine the extent of his injury.

The Angels designated Hiura for assignment Tuesday, Jeff Fletcher of The Orange County Register reports.

The return of Luis Rengifo (wrist) from the IL on Tuesday will leave Hiura without a spot on the active roster, and because he has no more options remaining, he will also lose his spot on the 40-man. The 27-year-old has slashed an incredible .360/.429/.853 through 85 plate appearances with Triple-A Salt Lake, though he managed just a .296 OPS in 10 games with the Angels.

Massey is out of the lineup for Tuesday's game against Arizona.

The lefty-hitting will dodge a matchup with lefty Jordan Montgomery on Tuesday. In Massey's place, Maikel Garcia will hold down the keystone.

Frazier is out of the lineup for Tuesday's game against Arizona.

Frazier's defensive versatility has earned him a regular spot atop the Royals' batting order, but he'll take a seat Tuesday against a left-handed pitcher. The lefty-hitting Frazier is batting 5-for-33 with a homer and five runs during July.

Semien went 1-for-5 with a solo home run in Monday's 4-3 extra-inning win over the White Sox.

Semien went deep in the third inning, his 14th home run of the season. The hit extended his on-base streak to 13 games, during which he's slashing .313/.431/.542 with three home runs, two doubles, seven RBI, 10 runs and 10 walks.

Gelof went 0-for-2 with a walk, a stolen base and a run scored in Monday's 4-0 win over the Astros.

Gelof has gone 1-for-15 over four games since the All-Star break, but he was able to make something of his one time on the bases Monday. The second baseman started July well but is now hitting just .172 this month. He's up to 12 steals, 12 home runs, 34 RBI, 37 runs scored and a .197/.261/.364 slash line through 80 contests overall.

Keith went 1-for-4 with a solo home run in Monday's 8-2 win over the Guardians.

Keith continued his breakout July, tallying his sixth home run of the month in the ninth inning. Since July 3, he has seen his season batting average rise from .229 to .251, and he has 10 homers, 38 RBI, 38 runs scored and five steals across 330 plate appearances.

Frazier will start at second base and bat leadoff in Monday's game against the Diamondbacks.

Though the versatile Frazier doesn't appear to have a permanent home at any one position, he's settled into an everyday role atop the batting order for Kansas City with MJ Melendez (ankle) landing on the injured list over the All-Star break. Frazier will serve as the Royals' table setter for the eighth straight contest, despite slashing an underwhelming .167/.259/.292 over the prior seven games.

The Astros designated Hensley for assignment Monday.

The transaction opens up a spot on the 40-man roster for utility man Aledmys Diaz, whose contract was selected from Triple-A Sugar Land. After reaching the big leagues for the first time in 2022, Hensley made two starts for the Astros' World Series-winning club later that fall, but he's struggled to stick around in the majors ever since. The 28-year-old posted a lowly .380 OPS over 94 plate appearances with Houston in 2023 and had spent the entire 2024 season at Sugar Land, with whom he slashed .234/.352/.376 with seven home runs and 17 stolen bases over 81 games before being designated for assignment.
