Aaron Krickstein, ranked No. 8 in the world, has withdrawn from next week's Sovran Bank Tennis Classic. He is still troubled by a sore right elbow he injured in the French Open that forced his withdrawal from Wimbledon.

"I was really anxious to play in Washington this year because it has a great field and I need to begin preparations for the U.S. Open," Krickstein said in a statement. "Hopefully, I will be healed by the end of the month."

Even with Krickstein's withdrawal, the Sovran still has one of the top fields in its history with No. 5 Andre Agassi, No. 6 Brad Gilbert, No. 11 John McEnroe and defending champion No. 14 Tim Mayotte.

The final of the tournament, scheduled for Sunday, July 22, is sold out. . . .

The postponed matches will be played tonight beginning at 6 p.m. on the Stadium Court, and the regularly scheduled matches will be played on the Grandstand Court, also at 6. Play will continue through Sunday.
