Rap superstar Lil Wayne may hail from New Orleans, but when it comes to baseball, it looks like he reps San Francisco.

At game six of the World Series playoff game between the San Francisco Giants and the St. Louis Cardinals, the rapper led the crowd at AT&T Park in "Take Me Out to the Ball Game" during the seventh inning stretch, while wearing a Giants jersey, gloves and hat.

"Just sung 'take me out to the ball game' @ the Giants game!!!," he tweeted after the game. "A true life highlight! I thank San Fran for rokkin wit me!"

So, why the San Francisco Giants? (Besides the fact that it's obviously the greatest team in the nation.) According to Lil Wayne's twitter account, the rapper is friends with infielder Ryan Theriot who left the Cardinals to join San Francisco this season. No word on how the two became friends, but Theriot is a Louisiana native, as well.

"Props to my homie Ryan Theriot and the Giants!!" tweeted Wayne after Friday's game five. "2 mo! Great game Zito!"

Two days later, he was on the field at AT&T.

The rapper is a frequent tweeter, especially when it comes to sports. Besides his shout-outs to the orange and black, Wayne has also recently tweeted about Louisiana State University football, swimmers Michael Phelps and Ryan Lochte, the NFL referee lockout, tennis player Andy Roddick and football player Eric LeGrand.
