Andy Murray reached the third round of the Rogers Cup in Canada after a 6-4 7-5 win over Spaniard Tommy Robredo.
World number three Murray had to play on to a second day after the contest was rained off at 4-4 on Tuesday.
The 28-year-old went a break down in the second set but recovered and faces Gilles Muller of Luxembourg next.
"It was tricky conditions, very windy, completely different to yesterday. When the shadow came across it became hard to pick up the ball," said Murray.
"I lost my timing in the middle of the second set but came up with some good shots towards the end.
