Tim Henman believes a second-round clash with world number one Roger Federer could provide a "great opportunity" to make an impact at the US Open.
The British number two's reward for beating compatriot Greg Rusedski in his delayed opening match at Flushing Meadows is a daunting date with the defending champion on Friday.
Henman needed one hour 55 minutes to reach the second round, overcoming Rusedski 7-6 (7-4) 6-2 6-3 for his seventh successive win over his rival.
"It's as tough a test as you can have," said Henman of his next opponent. "But it depends which way you look at it - a tough draw or a great opportunity."
Henman made a shaky start when his match, postponed on Tuesday due to rain, finally got under way last night.
He fell 3-0 down in the opening set but rallied to come through comfortably, although he admitted Rusedski's hip problem had been a factor.
"Once I got a set up I felt my game got better and better," Henman said.
"As he loses a little bit of strength in his hip, he wasn't coming forward so much. I can exploit that a little bit more.
"Yeah, I think as the match wore on, he was obviously getting a bit sore."
