Delay is out of the lineup for Tuesday's game against the Dodgers.
Delay had a brief run as the Pirates' No. 1 catcher earlier this month while Austin Hedges was on the 7-day concussion injured list, but Delay has faded back into a reserve role since Hedges was activated about a week and a half ago. Hedges has now picked up seven of the last nine starts at catcher for Pittsburgh.
