Heim is out of the lineup for Tuesday's game against the Red Sox.

Heim will give way to Carson Kelly behind the plate for the third time in four games. Heim is working through a minor skid at the plate, going 8-for-47 (.170) in his last 14 games.

Dingler is absent from the starting nine for Tuesday's game against the Mariners.

Dingler had started back-to-back games, but he'll yield to Jake Rogers behind the dish Tuesday. The 25-year-old Dingler is slashing .208/.269/.458 in 26 plate appearances for the Tigers.

O'Hoppe (knee) is expected to play Tuesday against Toronto, Sam Blum of The Athletic reports.

Manager Ron Washington said after the game that O'Hoppe was removed as a precaution, and he expects his starting catcher to be back in the lineup for the second game of the series. The team's training staff will likely check on O'Hoppe in the morning to confirm his availability for Tuesday's matchup.

Contreras went 2-for-3 with a two-run homer, a double and a walk during Tuesday's 5-2 loss to the Dodgers.

Contreras reached safely in three of his four plate appearances and produced the Brewers' only runs with a sixth-inning two-run shot off Joe Kelly. The 26-year-old is up to 14 home runs on the year and is 13-for-39 (.333) with 11 RBI and nine runs across 10 games in August.

O'Hoppe left Monday's game against the Blue Jays due to right knee soreness.

O'Hoppe went 0-for-2 at the dish with a strikeout before departing due to the injury. Matt Thaiss took over behind the plate in O'Hoppe's absence. O'Hoppe will be considered day-to-day until further notice.

Diaz went 1-for-4 with a three-run home run Monday against the Rays.

Diaz extended a modest hitting streak to six games with the three-run blast. He's also reached base safely in 16 of his last 17 with an on-base percentage of .413 and 10 extra-base hits including four homers, 14 RBI and 10 runs over that stretch.

The Guardians promoted Velazquez from Single-A Lynchburg to High-A Lake County on Monday.

Though the Guardians have seemingly closed the door on developing Velazquez as a catcher, the 19-year-old has cemented himself as one of the organization's top position prospects thanks to the slugging potential he brings as a first baseman. He put that power on display during his time with Lynchburg, notching 31 extra-base hits over 375 plate appearances while also keeping his strikeout rate (20 percent) in check. Velazquez will get a tougher test as he makes the move to the Midwest League, where he'll once again be one of the youngest hitters on the circuit.

Herrera is out of the lineup for Monday's game against the Rockies.

Herrera is on the bench for the second day in a row while the Diamondbacks hand another start at catcher to rookie Adrian Del Castillo, who has opened his big-league career by going 7-for-12 with three extra-base hits over his first three games. Even while Gabriel Moreno (adductor) is out indefinitely, Herrera looks like he could remain the Diamondbacks' No. 2 catcher, especially while Del Castillo is wielding a hot bat.

Del Castillo will start at catcher and bat sixth in Monday's game against the Rockies.

Del Castillo has opened his big-league career on a high note, going 7-for-12 with a home run, two doubles, one walk, five RBI and two runs through his first three games in the majors following his promotion from Triple-A Reno last Tuesday. The lefty-hitting Del Castillo could occupy the strong side of a platoon at catcher with the switch-hitting Jose Herrera while top backstop Gabriel Moreno (adductor) is on the injured list.

Fermin is absent from the lineup for Monday's game in Minnesota.

The Royals will go with Salvador Perez at catcher and Michael Massey at designated hitter for their series opener against the Twins. Fermin has gone just 3-for-20 at the plate across his last five games.
