With his siblings Zelda and Cody by his side, Zak Williams, the eldest son of Robin Williams, threw the ceremonial first pitch to Billy Crystal during Game 5 of the World Series on Sunday night in honor of his late father.
The tribute also included a video featuring highlights from Williams' films and snapshots from visits to AT&T Park, The Associated Press reports. In a statement, Zak, Zelda, and Cody Williams said: "For all of us, it is a tremendous delight and a little surreal to throw out the ceremonial first pitch of a World Series game for our team to our dad's best friend. We could not think of a better way to celebrate his memory. Let's go Giants!"
