Romine got his first nod of the year behind the plate on Monday against the Astros, putting down the signs for Pettitte. Yankees manager Joe Girardi said that he would "absolutely not" call pitches for Romine, preferring that he and Pettitte work together.
"Andy is pretty good about taking other players under his wing and letting them know what he wants to do," Girardi said. "He's not going to get flustered out there if they don't get in a rhythm right away. I think for that, it works pretty well."
Romine was called up from Triple-A Scranton/Wilkes-Barre after catcher Francisco Cervelli suffered a fractured right hand on Friday. In 14 games at Triple-A, Romine was batting .333 with a homer and four RBIs.
Though he worked with most of the Yankees' pitchers during Spring Training, Romine spent the last two days in the bullpen to get further reacclimated and said that he believes he has developed since making his big league debut in September 2011.
"I think I'm a little more calm out there," Romine said. "I know what to expect. I think that's going to allow me to slow the game down a little bit and actually think a little bit more. I'm excited."
