Murray has now won six matches in a row

The 18-year-old looked set to lose in his first outing since winning the San Jose title as he dropped serve twice in the opening set.

Schuettler served for the match at 5-4 in the second but Murray converted his second break point and took control.

He reeled off nine of the last 11 games for a 1-6 7-5 6-2 victory.

Murray will face South African lucky loser Rik de Voest, who made the most of Nicolas Kiefer's withdrawal through sinusitis by beating Jonas Bjorkman 6-4 6-3.

That extra confidence that I got from San Jose helped me Andy Murray

"I have got a lot more confidence after winning against guys like Hewitt and Roddick," said Murray.

"And in the quarters (in San Jose) I came back from a break and a set down against (Robin) Soderling, so I know how to get myself out of tough situations and today that was pretty important.

"Mentally I didn't feel like I was out of the match.

"I had a lot of chances in the second set to break him, I was 30-0 up a couple of times, I had another couple of 30-30 points and obviously my first break point at 5-4.

"I did feel like I was having a lot of chances but I was making a few too many mistakes and at 5-4, when it got to 30-30, that extra confidence that I got from San Jose helped me."

Meanwhile, top seed Roddick struggled past Australia's Wayne Arthurs in a second-round match which featured three tie-breaks.

The American lost the first 7-4, won a marathon second 11-9, before a comfortable 7-2 success in the decider.
