Federer said he and a number of the world's leading players would play special doubles matches Sunday. Tickets will be $10 for adults with children under 12 admitted free.
"I had the idea we could do something to help Haiti after the tragic earthquake," Federer said on the tournament's Web site Saturday. "So I spoke to some other top players (and) they said 'yes, we should do something.'"
He said he hopes for a big crowd and all proceeds will go to the Haiti earthquake victims.
"It's something as a tennis family we're very happy to do," Federer said.
