After five losses in six games, the Yankees have shaved their wonderful mustaches

The fun of the Yankees' so-called "Stache Squad" evaporated somewhere on the charter flight between Kansas City and Washington, with five losses in six games suggesting that someone should break out the razors.

Most of the Yankees were clean-shaven as they reported to Nationals Park on Tuesday, with Brett Gardner (above), Mark Teixeira:

And Stephen Drew all saying goodbye to their once-lucky soup-strainers: 

Dellin Betances was also among the bunch to get rid of his facial hair.

"It wasn't going to last forever," Gardner said. "Just a couple of guys talked about, maybe it was time. Maybe we'll start another one back at some point."

Gardner was the ringleader of the Yanks' mustache craze, which found its roots in a three-game sweep of the Rays at Tropicana Field from April 17-19.

Since 1973, the Yankees have had a well-known facial hair policy that only permits hair above the lip. Pushing it to the limit, the Yankees won 18 of their next 24 games, grabbing possession of first place in the American League East.

"We had fun with it while it lasted," Teixeira said.

There could be a few more players grabbing the after-shave. Andrew Miller, Jacoby Ellsbury and Masahiro Tanaka were among those clinging to the mustaches on Tuesday afternoon, but the clock seemed to be nearing midnight for those too.

"I'm not going to be the only one," Miller said.
