Federer leads their previous matches 9-1. They played twice last season on hard courts. Federer won both of them with Raonic taking 1 set. Not surprisingly his set was a tiebreak.
Raonic won his semi final with Tomic in 2 tiebreaks and breakers would seem to be his only hope today. Federer plays the big servers better than almost anyone else on the tour.
Hopefully Raonic can take the opening set for a better price on Federer.
