Wainwright, who Friday defeated 2001 Junior Amateur champion Henry Liaw of Rowland Heights, Calif., used birdies on the 8th, 10th and 16th holes to defeat Wittenberg, 3 and 2. The 6-2, 230-pounder from outside San Francisco totaled five birdies in the match.
I started thinking that it was possible to win but now Im a lot closer, Wainwright said. You cant make it to the final before playing in the semifinals. If I putt as well as I did this morning, I have a good chance.
Wittenberg, 17, who entered match play as the No.4 seed, was also a quarterfinalist in 2001, losing to eventual champion Liaw.
Beljan withstood a 2-down deficit after 15 holes and defeated Brian Harman, 15, of Savannah, Ga., the youngest remaining participant, in 21 holes.
Reynolds won holes 15 and 18, of a closely-contested match, to take a 2-up decision from Joe Panzeri, 15, of Boise, Idaho.
The 18-hole final is slated for 8 A.M. Sunday morning.
