The Marlins are back to carrying 12 pitchers, where they are more ideally suited.
The reason to go with an extra arm in Atlanta was because of back-to-back short stints from their starters last weekend against the Giants at Marlins Park. The San Francisco series depleted the bullpen, so to play it safe, a 13th pitcher was brought to Atlanta.
Miami ended up taking three of four from the Braves, and the starting pitching was solid.
Realmuto, making his second stint with the Marlins, is batting .301 with six homers and 46 RBIs for Jacksonville.
"He's coming in to give us some depth," manager Mike Redmond said. "We called up DeSclafani, because at the time, we needed some depth with our pitching."
In the series opener on Friday at Minute Maid Park, Jarrod Saltalamacchia was used as the designated hitter, with Jeff Mathis catching lefty Brad Hand.
"Here with the DH, it allows us with some flexibility to bring in another catcher," Redmond said.
