Rickie Fowler isn't afraid to fire back at social media trolls, and he proved it again after the second round of the Deutsche Bank Championship.
It all started with Twitter user @solzisswag tagging Fowler in a tweet, complaining that the three-time PGA Tour winner didn't sign autographs after carding a 71 on Saturday in Boston.
He also let the world know that he was switching allegiances to Jordan Spieth, no doubt a crushing blow to Fowler.
