There's an article in a non English language where federer commits to playing Toronto next week. even if he wins Olympics the field should be so weak it'd be mental not to pla it. Top guys can vulture too.
Well,all the top guys are commited to play but the decision to actually play the tournament will be made at the end of the week.
It`s tough to say right now how tired the players will be after Sunday.He can easily change his mind if he has to play 5 sets and then do lots of promotional stuff the next day.
