Prior to 2017, #TeamEurope's RogerFederer had never won consecutive five-set matches in his career. This year he's done so twice – at the AustralianOpen (semi-final bt #Wawrinka and final bt #Nadal) and at the USOpen this week (first round bt #Tiafoe, second round bt #Youzhny in the second round). Next stop, a third round meeting with Feliciano #Lopez. Will it be another five-setter?
