Carl Soderlund looked to be cruising to a win on No. 1 singles, leading 6-0, 5-0 in the second set. That's when things went bad for the junior, dropping the next seven points.
After a break before the third set, he came back and won six of seven games in the third set to clinch a Virginia victory of Stanford 4-2 on Saturday.
The match was moved inside shortly into singles because of the rain on Saturday with Virginia leading 1-0 after winning the doubles point.
The Cardinal responded to the move winning the first two singles matches with Sameer Kumar beating Gianni Ross on four 6-4, 6-1 and Timothy Sah beating Ryan Goetz 6-4, 6-1.
Aswin Lizen won the first singles point for the Cavaliers 7-6 (5), 6-2 to make it 2-2. Brandon Nakashima won on two 6-1, 4-6, 6-3. He came back from down 3-1 in the third set to win.
With the victory in the round of 16, the Cavaliers advance to face Wake Forest in the NCAA quarterfinals. It will be a meeting between the two teams that have won the last four and five of the last six national championships.
