Swisher said he believed Granderson's knee hit his and that they collided shoulder to shoulder, but Granderson said he couldn't recall what hit where and said that he would need to see it on a screen.
"I don't know. I feel fine," Granderson said. "I didn't have any grass marks on me, any dirt. I don't know what happened. That's why I've got to see it again."
Slow-motion replays showed that Granderson was calling for the ball, but Swisher was unable to hear him over the roar from the right-field stands and could not get out of the way.
"Tonight was loud. This place was rocking," Swisher said. "You've got a good series man, Yankees-Angels, lots of people are going to come out. Over there in right-center, you can't hear nothing."
Granderson was knocked into the padded outfield wall, while Swisher landed with his back on the warning track. Granderson quickly sprang to his feet in pursuit of the ball, which was retrieved in time to hold Trumbo to a triple.
"Everything happened so quick," Swisher said. "Next thing I know, I turn to look, and Curt's running after the ball. And I'm like, 'He's OK.'"
Trumbo scored a batter later on Howie Kendrick's sacrifice fly facing Phil Hughes, but as they returned to the dugout, Granderson and Swisher shared a laugh about their full-contact hit.
"He asked me after we got up, 'Did you call for that?'" Swisher said. "I was like, 'Did you hear me?' I'm just glad it was nothing [near the] head or anything like that, especially concussion stuff."
The play recalled a moment in the deciding Game 5 of the 2005 American League Division Series, in which Yankees center fielder Bubba Crosby and right fielder Gary Sheffield collided in pursuit of an Adam Kennedy drive at nearly the exact same spot.
"It gets loud out there," said Girardi, who was on the Yankees' bench in 2005 as a coach under Joe Torre, who coincidentally attended Monday's game as well. "They can't hear each other. That's what happens."
