Robin Williams' children and the late actor's best friend Billy Crystal paid a special tribute to their lost loved one on Sunday.
Zak, Zelda and Cody Williams took a moment to honour their dad ahead of a baseball game in San Francisco, which saw Robin's team the San Francisco Giants play against the Kansas City Royals.
Taking to the AT&T Park mound, Zak – the eldest of the siblings – threw the ceremonial first pitch to actor Billy, who caught the ball in his glove, leaving the stadium to erupt in joy.

Zelda and Cody, who were also dressed in white Giants jerseys with their father's surname printed on the back, watched the emotional display from the side.
Before the game, Robin's children had released a statement, writing: "We are honoured 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 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!"
Close friend Billy Crystal had the crowds chanting 'Play Ball!'
Photos and snippets from Robin's much-loved films played on the main centre screen of the stadium, while Billy – who starred with Robin in comedy Father's Day – had the crowd cheering "Play ball!"
A moment of silence was also held for the late actor and comedian, with Robin's children looking visibly touched by the outpouring of love and support in the stadium.
Following Robin's death on 11 August, tributes flooded in from fellow Hollywood stars and the actor's family and friends.

The Mrs. Doubtfire star was remembered in a private funeral, but also in the public sphere, with Billy commemorating his friend at this year's Emmy Awards. Robin was remembered in the "In Memoriam" segment, which commemorates late actors who have contributed greatly to television.
Billy, who spoke about the love and impact Robin had on his fans, was the "perfect choice" for the speech, said Emmy producer Don Mischer.
