The San Francisco Giants gave a touching tribute to late Robin Williams prior to game 5 of 2014 World Series by having Williams' three children out on the mound to throw the first pitch.

After the video board played a tribute to the late actor and comedian, William's son Zak, joined on the mound by his siblings Zelda and Cody, threw the pitch to their dad's best friend Billy Crystal.

The Williams family issued this statement:

"We are honored to be here in support of the tribute to our father, someone who loved his hometown and especially the Giants. For all of us, it is a tremendous delight and a little surreal to throw 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!"

Crystal also spoke to the crowd:

As part of the tribute, the team showed clips of Williams on the giant screen.
