Adams will start at catcher and bat eighth in Sunday's game against the Mariners.

Rodriguez (elbow) will begin playing catch soon, Noah Hiles of the Pittsburgh Post-Gazette reports.

Delay is eligible to return from the injured list in early June, though he'll likely require a lengthier ramp-up period.
