Bill Murray will throw out the first pitch and sing "Take Me Out To The Ballgame" during the seventh-inning stretch at Wrigley Field during the Chicago Cubs' season opener against the Washington Nationals on Thursday, according to a team source.

Murray, a Chicago native, has thrown out the first pitch before. He shook off his catcher, went to the big windup and threw the ball over the backstop before walking off the mound holding his rotator cuff.

The legendary comic actor is a long-time Cubs fan.
