Pospisil, the No. 2 seed from Canada, beat Taiwan's Lu 6-4, 6-7 (3), 6-4. The match ended on Lu's second double fault of the match.
The temperature was 95 degrees, with a heat index of 101. Pospisil looked unsteady on his feet after losing the second-set tiebreaker. Cramping in his legs caused him to fall to the court in the third set, but he continued without a delay.
