Bryant said the new location and attractive field combined to boost tickets sales 30 percent from last year.
“It’s worked to our advantage,” Bryant said. “Now we have some Olympics marketing with some sendoffs. The U.S. Olympic Committee has come in and is sort of making us part of their road to London tour. They’re going to do some road to London interactive things.”
Two-time defending champion Mardy Fish and Brian Baker, who advanced to the round of 16 at Wimbledon, also are in the main draw.
Fish, the No. 2 seed, beat Isner in the last two Atlanta finals.
The doubles team of Bob and Mike Bryan are the only members of the U.S. men’s Olympic team who are not competing in Atlanta.
There also are London-bound Olympians from other nations in the Atlanta field.
Kei Nishikori, the No. 3 seed, and Go Soeda will represent Japan in the Olympics.
Other Olympians in the field include: Alex Bogomolov Jr. and Dmitry Tursunov, Russia; Lukas Lacko, Slovania; Yen-Hsun Lu, Taiwan; and Gilles Muller, Luxembourg.
