"[Kessler's] got an awesome mustache, kind of encouraged everyone to grow one, and now it's like a team-building exercise to get a little push here in August and September," Chisenhall said.
"A lot of other teams have little stuff that they do, so we think that this might be our niche," said Jason Kipnis, who's sporting a fu manchu with side burns.
Chisenhall wasn't sure about Kipnis' facial hair yet: "He's got the whole, like, 'I drive a Harley' look going on."'
But Chisenhall did list a few team favorites.
"I'm more of a fan of the creepy mustaches, so like Tyler Holt has a pretty nasty one, Mike Aviles' is pretty pencil thin," Chisenhall said. "I like the traditional mustache, but if somebody wears one that probably shouldn't have a mustache, it really helps."
Clean-shaven manager Terry Francona expressed his indifference.
"As long as they're not breaking the law," Francona said. "Cleanliness is not mandatory, I don't care if they shower, whatever, just as long as they play good baseball. Not real worried about the facial hair."
