Knizner is out of the lineup for Thursday's game against the Guardians.

With Patrick Bailey returning from the injured list Wednesday, Knizner looks set to move back into the No. 2 role at catcher. While Bailey was on the shelf for the minimum 10 days, Knizner made six starts in eight games and went 2-for-18 with a solo home run, one walk and an additional run.

Herrera will start at catcher and bat ninth in Thursday's game against the Blue Jays.

Herrera will pick up his fourth straight start and looks set to operate as Arizona's No. 1 backstop for at least the next week after Gabriel Moreno (hand) was placed on the 10-day injured list Thursday. Though he's received positive reviews for his pitch framing and ability to control the running game, Herrera hasn't provided much of an impact at the plate over parts of four seasons in the big leagues. He's a career .199 hitter and has slugged just two home runs in 459 plate appearances.

Bailey went 2-for-4 with a run scored in Wednesday's 4-2 loss to the Guardians.

Bailey returned to action after being reinstated from the 10-day injured list Wednesday, following a six-game absence due to a neck strain. The 26-year-old singled in the third inning and added another one in the fifth before coming around to score on a two-run homer by Heliot Ramos. With that, Bailey delivered his sixth multi-hit performance of the season. He's now slashing .193/.251/.277 with 18 runs scored, 16 RBI, nine doubles, one home run and one triple across 184 plate appearances in 57 games this season.

The Diamondbacks selected Garcia's contract from Triple-A Reno on Thursday.

Garcia was up with Arizona briefly earlier this month, seeing action in one game as a defensive replacement. He will back up Jose Herrera at catcher while Gabriel Moreno (hand) is on the injured list.

The Diamondbacks placed Moreno on the 10-day injured list Thursday with a right hand contusion.

Moreno was first injured back on June 6 when a wild pitch struck his hand. He has been in and out of the lineup since then and unable to get over the hump with the injury, so the Diamondbacks have elected to give him some extended down time. He'll be eligible for activation June 27 and should be ready to go at that time. Jose Herrera will serve as Arizona's primary catcher while Moreno is out, and Aramis Garcia has been called up from Triple-A Reno to serve as Herrera's backup.

Alvarez is slashing only .191/.286/.265 over his last 20 games with one home run and three RBI, but the Mets believe he's close to emerging from his slump, Tim Britton of the Athletic reports.

The 23-year-old catcher began revamping his swing mechanics in the offseason, but a fractured hamate bone this spring derailed Alvarez's progress, and he's struggled to get comfortable at the plate since coming off the IL. "The past week, I feel like he's hitting the ball in the air, hitting the ball hard - something we didn't see early on when he got back from the injury," Mets manager Carlos Mendoza said Wednesday. "I like some of the takes with some of the breaking balls. I know he's working." The team has had internal discussions about optioning Alvarez to Triple-A until he turns things around, but a lack of catching depth in the organization makes that tricky, especially while he's still contributing defensively. Should that prove to be necessary, Luis Torrens would take over as New York's No. 1 catcher until Alvarez regains his confidence as a hitter.

Pages is absent from the lineup for the first game of Thursday's doubleheader versus the White Sox.

Ivan Herrera will start at catcher and Alec Burleson will serve as the designated hitter for the Cardinals in the first game of Thursday's twin bill. Pages is a good bet to be behind the dish for the second contest.

Smith hit a solo homer as a pinch hitter in a 4-3 win against the Padres on Wednesday.

Smith began the contest on the bench, continuing his regular routine of resting every three games. However, the star backstop was called upon to pinch hit with the game tied 3-3 in the bottom of the ninth inning and came through with a walk-off solo shot to right-center field. Smith extended his on-base streak to 10 games with the blast, and he's batting .378 with three home runs, 10 RBI and 11 runs scored over that stretch. As a pinch hitter this season, Smith has gone 4-for-7, and he's batting a robust .333 overall on the campaign to lead the National League.

Maldonado is not in the Padres' starting lineup against the Dodgers on Wednesday.

Maldonado will sit after going 1-for-4 with a double across the first two games of the series. Elias Diaz will serve behind home plate and bat eighth while catching pitches from Stephen Kolek.

Smith is not in the Dodgers' starting lineup against the Padres on Wednesday.

Smith will be on the bench for the start of Wednesday's game while Dalton Rushing serves behind home plate and bats ninth. Smith has reached base safely in each of his last nine starts, and over that span he has gone 13-for-36 (.361) with 10 runs scored, three doubles, one triple, two home runs and nine RBI.
