Stewart was in the lineup for Sabathia again on Sunday, the third straight start they have worked together. Sabathia entered Sunday's start 2-0 with a 4.11 ERA with Stewart, while he had a 6.75 ERA in his first two starts of the year with Russell Martin.
"He's not his personal catcher," manager Joe Girardi said. "At some point, I'm going to give Russ a day off. If I can, you like to keep that backup guy with one or two guys. It has just kind of worked out this way."
Stewart came back to the Yankees with the reputation as a strong defensive catcher with a skill for framing pitches, displacing Francisco Cervelli to Triple-A before the season opener. Stewart has also provided a bonus of unexpected punch, stroking three hits in 10 at-bats, including three RBIs on April 17 against the Twins.
