Worth a bet at nice odds, good situation for him coming in fully rested having skipped the Rogers Cup where you have Murray and Djokovic who just had a grueling 3hr match in Canada and have almost no rest time before this tournament kicks off.
Djokovic has had some elbow pain and has never won this tournament and Murray will be satisfied with winning Montreal and heading to the USO knowing he can beat Djokovic again so will he give everything to win Cincy? I doubt it his focus is probably on the US Open now.
Makes Federer a value play especially if he wants the 2 seed for the US Open he needs to win here, we all know Federer won't win another slam but he can still vulture these Masters 1000 events when the top guys aren't fully motivated.
