Arizona optioned Del Castillo to Triple-A Reno on Monday.

With top catcher Gabriel Moreno returning from the 10-day injured list Sunday, the Diamondbacks will roll with Jose Herrera as the No. 2 backstop. Del Castillo is slashing .313/.368/.525 over 87 major-league plate appearances this season, but he'll have an everyday role in Reno for the tail end of the Triple-A season. The move makes room on the Diamondbacks' 28-man roster for right-hander Scott McGough.

Barnes said Monday that X-rays showed a fracture in his left big toe in a different spot than his previous fracture, Bill Plunkett of The Orange County Register reports.

Barnes missed the minimum amount of time when he was placed on the 10-day injured list on Aug. 19 with the same injury. The 34-year-old catcher is expected to go on the IL again, per Fabian Ardaya of The Athletic, but it's unclear whether Barnes will miss more than the minimum 10 days this time around.

D'Arnaud is not in the lineup for Monday's contest versus the Dodgers.

Sean Murphy will start at catcher for Atlanta on Monday. He and d'Arnaud wound up splitting the catching duties during the four-game series with the Dodgers, with both making two starts apiece.

Murphy (knee) has yet to resume catching and isn't expected to be activated from the 60-day injured list before the season ends Sept. 29, Evan Webeck of the East Bay Times reports.

Murphy has resided on the IL since May 5 with a sprained MCL in his left knee. Though he avoided surgery and was expected to make a full recovery from the injury in six weeks, Murphy has been a slow healer, with the knee injury still presenting too much pain for him to resume squatting behind the plate. The knee sprain hasn't kept him from hitting, throwing and running, but the Giants aren't keen on activating the 33-year-old if he's available only as a designated hitter or pinch-hitting option. Murphy said that he expects to be ready to resume catching in spring training after getting a full offseason of recovery.

Haase went 3-for-5 with a two-run homer and two runs scored in Sunday's loss to the Diamondbacks.

Haase did damage in the sixth inning with a two-run blast to left off of Kevin Ginkel. It was his second time with three hits in a game this season and second home run over his last three starts. He's made just three starts since the beginning of September and is up to five homers, 13 RBI and nine runs scored for the year.

Stallings went 1-for-3 with a solo home run and a walk in Sunday's 6-2 loss to the Cubs.

Stallings has gone 14-for-55 (.255) over 17 contests since the start of August as Colorado's backup catcher. He has four homers in that span and a career-high nine on the year, offering a bit of pop despite limited playing time. Overall, he's maintained a .261/.358/.455 slash line with 35 RBI, 27 runs scored, 14 doubles and one triple over 258 plate appearances.

Barnes exited Sunday's contest with Atlanta in the fifth inning with a left big toe contusion.

Barnes was forced to the leave the game before his second at-bat with a familiar injury. The catcher had a fracture in the same toe in August, and it's unclear how long he could be unavailable for. Will Smith replaced him behind the plate and will continue to get the lion's share of work at catcher moving forward.

Smith is out of the lineup for Sunday's game against Atlanta.

Smith will receive some routine maintenance after he had started behind the plate in each of the Dodgers' last three games. Austin Barnes will handle catching duties for the Dodgers in the series finale in Atlanta.

Murphy is out of the lineup for Sunday's game against the Dodgers.

Murphy had started behind the plate in five of the past six games, but he'll likely be in store for a role reduction after Travis d'Arnaud (personal) returned from the paternity list Thursday. Despite getting more consistent at-bats of late, Murphy is still hitting just .080 in September and a career-worst .203 on the season.

Higashioka is out of the lineup for Sunday's game against the Giants.

Higashioka will receive a breather in the series finale after he had started at catcher in four of the Padres' previous five games. Elias Diaz will step in behind the plate for San Diego.
