Bart went 1-for-4 with a walk and two runs scored across both games of Saturday's doubleheader against the Nationals.

Bart was activated from the injured list Friday but didn't return to the lineup until the first game of Saturday's doubleheader. The Pirates have a crowded rotation at catcher that also includes Yasmani Grandal and Henry Davis, though Bart has hit well enough this season to also get looks as the team's designated hitter.

Lee (back) will start behind home plate and bat fifth in Sunday's game against the Red Sox.

Lee will return from a two-game absence after he was scratched from Friday's lineup due to back tightness. Lee will do the catching for starting pitcher Chris Flexen in the series finale.

Alvarez is out of the lineup for Sunday's game against the Reds.

Alvarez started the first two games of the series but will sit for the finale after going 0-for-5 with two walks, a hit-by-pitch and two strikeouts. Luis Torrens will step in behind the plate to catch for righty Luis Severino.

D'Arnaud is not in the starting lineup for Sunday's series finale against the Blue Jays.

D'Arnaud will get a breather after going 2-for-8 with one run scored across the first two games of the series. Sean Murphy will start behind home plate and bat fifth against Toronto right-hander Yariel Rodriguez.

Dingler went 1-for-3 with a double and an RBI in Saturday's 2-1 win over the Athletics.

Dingler came into the contest having gone 0-for-19 over his previous six games. The young catcher snapped that streak, though he's still batting just .141 for the season with a 33 percent strikeout rate. Until Dingler can become more consistent at the plate, his fantasy ceiling will remain capped.

Herrera went 1-for-3 with an RBI and a run scored in Saturday's 11-5 loss to Houston.

One day after being removed from a game due to a head injury, Herrera returned to the lineup. He had been hit on the top of his catching helmet by the backswing of Kyle Tucker's bat during Friday's contest and was removed for precautionary reasons. Herrera cleared testing protocols following the game and was able to resume play Saturday.

McCann went 1-for-2 with an RBI single in a loss to the Tigers on Saturday.

McCann drew one of his infrequent starts behind the plate and drove home the Athletics' only run with a fifth-inning single that plated Zack Gelof. The rookie had last accounted for an RBI on July 28, and he's sporting a .248 average and .705 OPS over his modest 140 plate appearances this season.

Pages went 1-for-3 with a two-run home run in Saturday's 2-0 win over the Mariners.

Pages came through in the eighth inning, launching a Logan Gilbert slider over the left-field fence for the only scoring play of the game. Pages has gone 4-for-14 (.286) over four games in September, but three of those hits have been homers. The catcher is up to six long balls, 22 RBI, 17 runs scored, one stolen base and a .245/.287/.396 slash line through 172 plate appearances this season.

Contreras went 2-for-3 with a two-run homer and a walk in Saturday's 5-2 win over the Rockies.

Contreras took Ty Blach deep for a two-run homer in the third inning and set a new career high for homers in a season after he hit 20 in 2022 with Atlanta. Contreras' multi-hit effort broke him out of a 0-for-19 slump over his last six games. The 26-year-old catcher has found his power stroke as of late with 10 home runs since the beginning of August, including four in his last 10 starts.

Naylor isn't in the Guardians' lineup for Saturday's game versus the Dodgers.

After going 0-for-5 across his last two games, Naylor will take a seat Saturday while Austin Hedges catches for Gavin Williams and bats ninth.
