Stewart was placed on the 10-day disabled list Tuesday with a strained left hamstring.

EDGE Analysis

While it was originally thought Stewart wasn't going to need a trip to the DL, the Pirates have decided to err on the side of caution with the 35-year-old backstop. Stewart was slashing .225/.295/.350 through 16 games (40 at-bats) before landing on the DL. Stewart will be eligible to return on June 8, while Elias Diaz was recalled from Triple-A Indianapolis and will serve as the Pirates' backup catcher in his absence.
