Week-long tickets and some single-session tickets for the BB&T Atlanta Open will go on sale March 5.

The tennis tournament will be held at Atlantic Station for the second consecutive year. Tournament dates are July 20-28.

The field got a little tougher with the additions or Ryan Harrison and his brother Christian, who will play singles and doubles, as well as South Africa’s Kevin Anderson, a top-30 player in the ATP’s world rankings. Ryan Harrison is one-half of the defending tournament doubles team.

Already committed to play are the Bryan Brothers, the top doubles team in the world, as well as former Georgia standout John Isner, who at No. 15 is the world’s top-ranked American and highest-ranked singles player to commit to the tournament, and two-time BB&T champ Mardy Fish.

Andy Roddick, since retired, won last year’s event.
