Still lacking fitness after undergoing knee surgery three
months ago, Tsonga looked jaded throughout the two-hour match
but sealed victory with a 7-1 win in a final-set tiebreak.
"It was a very difficult match, I didn't play my best
tennis," Tsonga said. "I won, that's the main thing, because Lukas was playing
some good tennis. It's a good victory for me because I haven't
played so much.
"I served well, I was there, I fought, and I won."
Since he reached the final of the Australian Open in
January, Tsonga's season has been blighted by injury, causing
him to miss the French Open and Wimbledon. He has played only
last month's U.S. Open since his knee operation.
The lanky Monfils injured his leg after falling over several
times during the match but was pinning his hopes on a speedy
"I don't feel so good now but we'll see tomorrow," he said.
"I played solid and consistent. I broke him early in the match
and played OK after that."
