After a two-hour rain delay that interrupted his match, Austin Krajicek, the fifth seed from Bryan, Texas, advanced to Saturday\'s 18 semifinals with a 6-1, 3-6, 6-2 win over Rhyne Williams (12) of Knoxville, Tenn.
The match was Krajicek\'s third three-setter of the tournament.
"I wasn\'t too upset that it rained because I had the momentum in the first set and then it kind of shifted over to his side a little bit," said Krajicek.
After exchanging breaks in the third set, Krajicek held serve for 2-2.
"It was a big game," he said. "That was probably \'I felt I could win the match\' difference there because he had the momentum back and I grinded out that game and that kinda gave me some momentum going into his game."
Krajicek plays top-seeded Ryan Harrison in the semis.
