Juan Martin del Potro remained on course for a Sunshine Double when he outlasted Milos Raonic in a marathon quarter-final at the Miami Open on Wednesday.
Del Potro, who claimed the Indian Wells title earlier this month, dominated two tie-breaks to secure a 5-7 7-6 (7-1) 7-6 (7-3) victory.
"I love to play in matches like this," a visibly weary del Potro said. "We both played well, the difference was perhaps that I just played better in the tie-breaks.
"I am tired now, but at least I have a day off to prepare for Friday. It's going to be important that I recover physically and mentally because that was a real battle."
Raonic, the world No 25, took the first set 7-5 after breaking on the 12th game of the set.
The pair were strong on serve in the second as it went to a tie-break, but the Canadian was broken four times as Del Potro took the set 7-6 (7-1).
The third set started with four games which went against serve, and again went to a tie-break, where Del Potro broke three times to win 7-3.
In the last four, Del Potro will face American John Isner who progressed to the semi-finals with a comfortable straight-sets victory over Chung Hyeon.
