NOTTINGHAM, England (AP) Gilles Muller of Luxembourg reached his second semifinal on grass in three weeks at the Nottingham Open on Thursday.

Muller, serving superbly, aced Alexandr Dolgopolov of Ukraine 14 times in a 6-3, 6-4 win. He lost only three points off his first serve.

In the short grass season, he has been runner-up in the Netherlands, and a quarterfinalist at Queen's last week. He's into the Nottingham semifinals for the third time.

The eighth-seeded Muller will play second-seeded Pablo Cuevas, who was into his first ATP semifinal on grass. The Argentine came to Nottingham with two career wins on grass and has won three in a row this week.

Cuevas saved a match point and beat Marcos Baghdatis of Cyprus only on his fifth match point to prevail 6-4, 4-6, 7-6 (8).

Cuevas saved a match point serving at 4-5 in the third set. In the tiebreaker, Baghdatis led 4-0, Cuevas pulled ahead 6-4, and couldn't finish it off until it was 9-8.
