"Today isn't as much about [Cozart] getting a rest as much as I need to play Valdez," Reds manager Dusty Baker said. "He's played less than anybody on the team."
Valdez came in batting .195 in 21 games this season. Cairo, who entered batting .143 in 16 games, started on Saturday but exited in the fourth inning as part of a double switch.
"I tried to get Miggy at-bats the other day, but I had to take him out after only two at-bats, which I hated to do. But I needed that spot for pitching," Baker said.
