Nationals Pitcher Shaves Mustache, Gains Ability To PitchDavid Matthews8/06/10 3:30pm18EditPromoteGo to permalink Collin Balester was having trouble. He had a great mustache, but he wasn't pitching well at all. He had beaned Rickie Weeks and Mark Reynolds in the head. He needed to make a radical change. The mustache, unfortunately, would have to go.
