BANGKOK (AP) American Donald Young beat defending champion Guillermo Garcia-Lopez of Spain 6-1, 6-7 (0-7), 7-5 Thursday in the second round at the Thailand Open.

The 22-year-old Young secured a place in his second ATP quarterfinals, having reached the semifinals in Washington last month.

It feels great to get a win like that,'' said Young, who missed an early chance to wrap up the match when serving at 5-3.He won the tournament last year. It's a great scenario for me, it's great to move on into the quarterfinal.

``Holding my nerve was the key. I tried not to get down when I had the chance to serve for the match. I was up quite early in the first set. I had chances to break him in the second, but I didn't make it. I just tried to stay focused with the task in hand.''

Young, ranked No. 55, will play Go Soeda of Japan, a 6-2, 7-6 (9-7) winner over Tobias Kamke of Germany.

Andy Murray reached the quarterfinals by defeating Michael Berrer of Germany 6-4, 6-2.

The fourth-ranked Murray, who had a bye in the first round, will face either Grigor Dimitrov of Bulgaria or Simone Bolelli of Italy.

I started well and was serving well throughout the match,'' Murray said.I got jet lag and didn't sleep well for a few days.''

The match started after a ceremony presided over by Thai Prime Minister Yingluck Shinawatra.
