Anna wasn't injured when she was blown out of the US Open by Angie Widjaja last summer, selesrules. Maybe beating Anna Smashnova in California counts to you as a "great" result, but to most observers, to find any result approaching "great" on Anna's resume, you have to look a few years farther back than last summer. Lipton 98, Wimbledon 97, now THOSE qualify as great results.
I don't think Anna will be back to play singles tennis except in exhibitions and suchlike. Her nerves are shot for bigtime tennis, and too many younger and more eager players have passed her by. But her fans can look forward to seeing her play in such events as Arthur Ashe Kids' Day at the Open this year, maybe some doubles in WTA events, etc. I can't see her disappearing from the tennis scene entirely any time soon.
