Left fielder Christian Yelich also was given a day off, and Reed Johnson started in his place.
The Marlins are at the midway point of their nine-game homestand, and they will immediately head to the West Coast to play an 11-game road trip in consecutive days.
Redmond said he is considering giving Giancarlo Stanton a day off on Wednesday in the series finale with the Mets. The team also hopes to give center fielder Marcell Ozuna a breather soon.
"We're going to mix a few guys in," Redmond said. "When you are playing 20 straight days, you don't have the luxury of days off to keep guys fresh."
Saltalamacchia, 8-for-14 so far on the homestand with two homers, is scheduled to start on Sunday with Jose Fernandez pitching.
