South African Kevin Anderson advanced to the second round, but seventh seed Alex Bogomolov Jr. of Russia was ousted Monday on a rainy day at the Atlanta Open tennis event.
Anderson, seeded fifth, defeated Italian Paolo Lorenzi, 6-4, 6-3; while 19- year-old American wild card Jack Sock topped Bogomolov, 6-2, 4-6, 6-4 on the hardcourts at Atlantic Station.
Also Monday, France's Nicolas Mahut topped Chile's Paul Capdeville, 6-3, 3-6, 6-4; Steve Johnson beat fellow American Donald Young, 6-3, 3-6, 6-3; Russian Igor Kunitsyn upended American Brian Baker, 6-4, 6-7 (3-7), 6-3; and Gilles Muller of Luxembourg got by Australian Marinko Matosevic, 7-6 (7-5), 6-4. The Baker match didn't end until 1:21 a.m. (et) due to the wet conditions that delayed play earlier in the evening.
This week's top seeds are last week's Newport champion John Isner and his fellow American Mardy Fish, who has beaten Isner here in the last two all- American Atlanta finals.
Former world No. 1 Andy Roddick is also in the draw here as a fourth seed.
The winner of this $477,900 tournament will pocket $86,270.
