"I was excited before the game," Murphy said. "My nerves calmed down after the first inning and I was fine. I settled down and it was a lot of fun. I wish we were on the winning end."
Murphy has been mostly catching bullpen sessions this month, but Chris Stewart has already played in 100 games, well exceeding manager Joe Girardi's original estimate of about 60. Yankees catcher Austin Romine is also recovering from a concussion.
"It's been a grueling schedule here, and I just felt that we had to give Stew a little bit of a break today," Girardi said. "I won't be afraid to use him later. I'm not ready to use Romine yet, so the kid was called upon."
A second-round pick (76th overall) in the 2009 First-Year Player Draft, Murphy played in two games against the Red Sox at Yankee Stadium earlier this month.
He batted a combined .269 with 12 home runs and 46 RBIs this season between Double-A Trenton and Triple-A Scranton/Wilkes-Barre, and Girardi described Murphy as a "cool and calm" receiver behind the plate who "didn't look overwhelmed" by the situation.
"I don't think he gets too emotional back there," Girardi said. "He's improved a ton as a catcher over the couple of years that I've seen him. He swings the bat well. I think he retains [information] pretty well, and obviously that's important."
