21-year-old Goffin defeated last year's sensation Tomic, the 20th seed in Wimbledon, 3-6, 6-3, 6-4, 6-4 in 2 hours and 33 minutes. The Belgian next meets the American qualifier Jesse Levine. Goffin is the world's number 70, Levine is just outside the top-100 at 106.
Goffin received a wild card for Wimbledon after his excellent run in the French Open, where he made it into the last 16 only to be stopped by Roger Federer.
In other action today, Olivier Rochus was ousted by Spain's Nicolas Almagro. The two were at 2 sets and 2 games all when play was suspended last night. Today, Rochus lost the remaining set 6-4.
Still, there was also good news for Olivier Rochus. The Belgian Olympic Committee decided to send him and Steve Darcis to the Olympic Games.
The two had met the international olympic criteria, but not the BOIC's individual criteria. Rochus next threatened to take the matter to court, but the BOIC has now decided to grant him an olympic ticket anyway.

"I enjoyed playing here today. These are the kind of matches that you do it for. If you can win like this, then tennis is a nice job."
Wickmayer next meets Galina Voskoboeva of Kazachstan. "Not to be underestimated."
In all, 5 of the 7 Belgians advanced to the second round of the singles tournament: Kim Clijsters, Yanina Wickmayer, Xavier Malisse, Ruben Bemelmans and David Goffin. Olivier Rochus and Steve Darcis were ousted.
