Milos Raonic began his Australian Open with a 7-6 (2), 6-1, 4-6, 6-2 defeat of Spain's Daniel Gimeno-Traver on Tuesday to reach the second round in sweltering temperatures.
Raonic, the 11th seed from Thornhill, Ont., was tested for nearly two and a half hours in the demanding heat that hovered just above 40 C.
The heat was even too much for one of the ball kids, who had to leave the court in the middle of the match. Raonic finally put away the victory on his fifth match point against an opponent ranked 77th in a first-time meeting.
Raonic took the victory with 21 aces, striking 48 winners and breaking on 7-of-20 chances. The 23-year-old was frustrated as he tried to close out the contest but finally got the job done when he broke the Spaniard's serve.
