Roddick into 3rd round

"That's all I can do - and hopefully just play well." Andy Roddick clocked his eighth consecutive career victory over France's Sebastien Grosjean winning 6-4, 7-6 (7-3) to earn a place in the third round.

Roddick, seeded sixth, fired over the last of his nine aces to clinch the win in 87 minutes with 34 winners. He never faced a break point.

The American said he was feeling his body as a long season nears the end.

"My knees are hurting a bit, it's just a bit of tendinitis, nothing serious," Roddick said. "At the end of the year after a long schedule, you have your good days and your bad days. I don't know that today was great."

Watching from the box was Roddick's coach Jimmy Connors, keen to help his man into next month's season-ending Masters Cup event in Shanghai.

Roddick needs to win the Madrid event in order to qualify for Shanghai, a tall order in a crowded field of top ten players.

Roddick improved his modest Madrid record to 2-3. He came to Spain after reaching the Vienna semi-finals last weekend.
