ST. LOUIS (KSDK) - One of the more popular Cardinals fans in the land, "The Hat Guy," was at Joe Buck's Restaurant Monday afternoon for our Opening Day Pep Rally and showed off some of his recent pieces for Mike Bush.

The Hat Guy (aka Tom Lang) used his Opening Day 2013 hat to celebrate both the Clydesdales and the life of Stan Musial. Lang let Mike Bush wear a special "Infield Fly Rule" hat he made after last season's controversial NLCS Wild Card Game between the Cardinals and Nationals. And lastly, Lang displayed his "Gold Glove Hat," which he'll wear at a future game when the team honors catcher Yadier Molina.
