Caratini is starting at catcher and batting sixth in Saturday's game against the Reds.
Willson Contreras will be out of the starting lineup for the second day in a row, so Caratini will start behind the plate once again. The 25-year-old went 0-for-2 with two walks in Friday's loss, and he's slashing .400/.545/.640 across 25 at-bats this season.
