Caratini is out of the lineup for Sunday's game against the Diamondbacks.
Caratini will cede catching duties to Austin Nola in the series finale after going 0-for-3 with a strikeout in Saturday's 6-2 win. Since Nola was reinstated from the 10-day injured list July 22, Caratini has picked up seven starts at catcher to Nola's eight, so the Padres seem content to deploy a timeshare at the position.
