Grandal is not in Wednesday's lineup against Tampa Bay, J.P. Hoornstra of the Southern California News Group reports.
Grandal is just getting a normal day off, despite his recent power surge. A.J. Ellis will take over behind the plate and will bat eighth.
Perez is not in the lineup for Wednesday's game against the Nationals, according to Ryan Lewis of the Akron Beacon Journal.
Perez started the last three games behind the plate, but he will be held out Wednesday with the Indians playing a day game following a night game. Chris Gimenez will serve as the Indians' catcher in Perez's place.
Ramos went 2-for-4 with a double, two runs scored and an RBI as the cleanup hitter in Tuesday's loss to the Indians.
His stay in the No. 4 spot in the order may not last long, as Bryce Harper was shifted up to the two-hole and went 0-for-5, but Ramos has been productive all season no matter where he's been hitting. The catcher now sports a .339/.390/.546 slash line on the year with 15 home runs and 54 RBI.
Posey went 2-for-4 with a walk, a steal and two runs scored Tuesday against the Reds.
Posey doubled his previous career high with his sixth steal, and padded his OBP by reaching base three times in five appearances. The catcher's .289/.362/.465 line is only inferior to last season's .318/.379/.470 showing due to a slight dip in BABIP from .320 to .297.
Grandal went 1-for-3 with his 14th home run of the season Tuesday against the Rays.
That's eight homers in the past month for Grandal, who is just two shy of last season's career-high total. The recent power surge has raised the catcher's slugging percentage to .430, but a dismal .227 BABIP has suppressed his average to a meager .211 mark.
Molina caught game 1 of the doubleheader, and will get the second contest off as Alberto Rosario gets the nod behind the plate. He went 2-for-4 with a double in the first game Tuesday, to improve his batting average to .283 on the season, while adding on three home runs and 29 RBI.
Rivera went 1-for-2 with a two-run homer and a walk Tuesday against the Cardinals.
Rivera left the yard for the fourth time this year in the fourth inning to pull the Mets within one run in a losing effort. The part-time backstop has homered in two of his seven starts this month, and he's now slugging .356 in 92 at-bats on the season.
Leon will start behind the plate Tuesday against the Tigers after Ryan Hanigan was scratched due to illness, Tim Britton of the Providence Journal reports.
Leon will bat eighth while catching knuckleballer Steven Wright during Tuesday's contest. Wright has normally been caught by Hanigan throughout the season, but Leon will slide back into the lineup after going 2-for-4 with an RBI on Monday.
