Smith isn't in the lineup for Tuesday's game against the Cardinals.

Smith will step out of the starting nine Tuesday after going 0-for-3 with a walk in Monday's loss. Dalton Rushing will get the nod to start behind the plate instead and catch for starter Emmet Sheehan.

Wells isn't in the lineup for Tuesday's game against the Rangers.

Wells will take a seat Tuesday after going 1-for-5 with a run scored during Monday's series opener. Ben Rice will catch instead for starter Will Warren and bat second.

McCann isn't in the lineup for Tuesday's game against the Padres.

The Diamondbacks have begun to use McCann behind the plate every other day since the start of August, and Tuesday will mark a day off for the 35-year-old backstop. Jose Herrera will start at catcher instead and bat ninth.

The Blue Jays designated Sanchez for assignment Tuesday, Keegan Matheson of MLB.com reports.

The Blue Jays had no use for Sanchez following Alejandro Kirk's return from the injured list Sunday, so the former will now lose his place on the MLB and 40-man rosters. Buddy Kennedy was selected from Triple-A Buffalo to fill the vacant spot.

Stephenson is absent from the lineup for Tuesday's game versus the Cubs.

It's a routine day off after Stephenson caught each of the previous two days. Jose Trevino is behind the dish and batting eighth for the Reds on Tuesday.

Dingler is absent from the lineup for Tuesday's game versus the Twins.

He'll get a well-deserved break after starting each of the previous four contests at catcher. Jake Rogers will be behind the dish and bat ninth while Dingler rests.

The Athletics recalled MacIver from Triple-A Las Vegas on Tuesday.

The 28-year-old was optioned to Las Vegas in late July but will make a quick return to the majors to replace Austin Wynns (abdomen) on the active roster. MacIver has handled himself well at the plate in his first 17 big-league games this season with a .737 OPS, but he isn't likely to receive regular playing time while serving as the backup to starting catcher Shea Langeliers.

The Athletics placed Wynns on the 10-day injured list Tuesday with an abdominal strain.

He'll be shelved until at least mid-August while recuperating. Willie MacIver is up as Wynns' roster replacement and will serve as the backup catcher behind Shea Langeliers.

Stephenson went 1-for-4 with a solo home run Monday in a 3-2 win against the Cubs.

Stephenson got the scoring started in the contest with a 389-foot solo shot in the second inning, giving him nine long balls on the campaign. The backstop has reached base in nine of his past 17 plate appearances, including six times via walk. Stephenson has a solid 11.7 percent walk rate on the season, though he's also posted an ugly 34.7 percent strikeout rate.

Diaz went 2-for-4 with a double and two RBI in Monday's 8-2 victory over the Marlins.

The Houston backstop picked up his 16th two-bagger of the season off Miami starter Sandy Alcantara in the fourth inning to plate two runs. Diaz has been a steady contributor since the All-Star break, hitting .300 (18-for-60) with five doubles, two homers, nine RBI and seven runs scored across 16 contests. The 26-year-old is slashing .255/.284/.420 with 15 homers, 47 RBI and 40 runs scored in 401 total plate appearances.
