WIMBLEDON, England (AP) There was a moment when Bernard Tomic didn't think he'd get past the first round of qualifying for Wimbledon, much less into the second week of the tournament.

Now he's the youngest player in 21 years to reach the fourth round of the grass-court Grand Slam after the biggest victory of his career Saturday.

The Australian beat fifth-ranked Robin Soderling 6-1, 6-4, 7-5 in the third round. He is the first 18-year-old since Michael Chang and Goran Ivanisevic in 1990 to reach the second week at Wimbledon.

Tomic will overtake Lleyton Hewitt as Australia's highest-ranked player.
