Gilles Simon called his 0-6, 6-0, 7-6 (0) win against Gael Monfils in Madrid a "very, very strange" match, reflecting the scoreline.
The Frenchman joked that he would have to watch the match again to know what had happened.
"One of the most strange matches I've played," he told reporters following his win. "It was a very, very strange match. Neither of us played good at the same time. Neither of us played good ... It was hard to find rhythm."
