Lewis has since apologized on Facebook, saying his nerves got the best of him.

"All I can say is I'm sorry and ask for the Nation's forgiveness. My nerves got the best of me and I am completely torn up about what happened. America is the greatest country in the world. The Star-Spangled Banner means so much to so many, including myself. I hope everyone can understand the intensity of the situation and my true intent of this performance. I hope that the Nation, Major League Baseball and the many fans of our national pastime can forgive me," said Lewis.

The pre-game festivities also included a heartwarming moment as Robin Williams' son threw out the first pitch, with Billy Crystal on hand.
