Phillies fans who watch the show on FX remember the episode when Philadelphia native Rob McElhenney's character, Mac, wrote a love letter to Utley. Utley said he first saw the episode when a friend e-mailed him a link of the scene, where Kaitlin Olson's character, Dee, read the love letter.
"I thought it was pretty funny," Utley said.
Utley said the show contacted him a while back about appearing in an episode.
"I've watched the show a couple times and it's a funny show," Utley said. "I figure I'd give it a shot."
Utley said he is unaware of any love letters from real-life Macs.
