Australian youngster Bernard Tomic produced the biggest upset of the Wimbledon men's singles so far here Saturday, dumping out Swedish fifth seed Robin Soderling 6-1, 6-4, 7-5. The 18-year-old world number 158 served notice of his talent with a superb display to send Soderling spinning out of the third round and will now play either Jurgen Melzer or Xavier Malisse in the last 16.
