The first set told the tale; every tiebreak would go against the run of play.
Raonic made the first break of the match at 2-1 in the second set. But serving at 4-3, the famously over-analytical son of engineers was agitated over an out call that came from the sideline, rather than baseline, judge – though the call itself was correct.
Wawrinka levelled for 4-all and looked on course to pinch another tiebreak. But at 3-all he made a strangely tentative miss on his favourite down-the-line backhand to go down a mini-break. Raonic iced it with two aces and another big serve on set point.
In the third set, it was the Swiss who dominated on serve, dropping just three points. He was the first to arrive at set point, at 6-5 in the tiebreak, but it was on the Raonic serve, and the big man played a clutch serve-volley. Three set-points apiece flitted back and forth before Raonic got the first on his racquet and landed a service winner to take it 13-11, the tiebreak alone stretching to nearly 20 minutes.
Despite the still indoor conditions favouring Raonic, it was Wawrinka who served for the fourth set at 5-3 as the crowd settled in anticipation of a five-setter. The Canadian lifted when the momentum was against him to turn the match. He then recovered from a 0-2 deficit in the tiebreak, hitting a final booming ace to bring up match point.
