DELRAY BEACH, Fla., Feb. 28 (UPI) -- John Isner and Tommy Haas, the tournament's top two seeds, moved into the quarterfinals Thursday at the rain-delayed Delray Beach Championships.

Rain washed out most of Wednesday's schedule, but the quarterfinals were all set Thursday and will be played Friday.

The top-seeded Isner defeated Go Soeda 7-6 (7-2), 6-2 in the final match of the evening to create a quarterfinal matchup with defending champion Kevin Anderson.

Anderson, the No. 6 seed, survived a battle with Yen-Hsun Lu 6-4, 3-6, 6-3.

Haas was a 6-4, 6-1 winner over Denis Istomin and will next meet Ivan Dodig, who got past Evgeny Donskoy 6-3, 7-5. Haas won this event seven years ago.

Qualifier Ernest Gulbis surprised No. 3 seed Sam Querrey in the second round and his quarterfinal opponent will be Daniel Munoz-De La Nava, who outlasted Xavier Malisse 7-6 (7-3), 3-6, 6-3.

The other quarterfinal will send Edouad Roger-Vasselin against Ricardas Berankis. Roger-Vasselin eliminated Ivo Karlovic 6-4, 75 and Berankis rallied to defeat Jack Sock 3-6, 6-4, 6-1.

Sock reached the quarterfinals last week at the U.S. Indoor Championships to climb from 168th in the world to No. 130.
