Shanghai: Andy Roddick enjoyed an easy ride into the second round of the Shanghai Masters as German Philipp Kohlschreiber was unable to continue in a 6-3, 2-1 victory for the American tenth seed.
"We`ve all been on the bad side of having to pull out of a match, it`s not fun," said Roddick, who lost his opening match here in 2009 and has tumbled out of the top 10.
"But I thought I hit the ball well in what we did play today. I started to hit pretty well last week also, even though I lost the match to Gaël (Monfils in Tokyo).”
"I`m glad that I can get through today and keep trying to build on it."
Chinese tennis showed robust health as unheralded Bai Yan, number 465 in the world, upset veteran Czech Radek Stepanek 6-3, 6-4 to move into a match with fourth seed Andy Murray.
Bai, 21, is riding high from titles at a pair of low-level Chinese Future events in recent weeks while Murray is struggling to escape another slump after a quarter-final loss last week in Beijing against Ivan Ljubicic.
"I`ll just do my best job and give my best performance," said Bai. "All I know is that I can probably put him under some pressure."
Bai has watched Murray numerous times on television, even if the Scot will likely have no idea who his opponent is.
"He`s a talented player, much better than me, I think. But I hope to learn from him in our match and I think it will be a good opportunity for me," said Bai.
Bai`s only other ATP appearance came in Beijing two years ago, when he lost in the first round to Japan`s Go Soeda.
Wimbledon marathon man John Isner meanwhile made a recovery, sending over 24 aces in a defeat of Lukasz Kubot 4-6, 7-6 (11/9), 7-6 (9/7).
