The 35-year-old Kuehne, best known for losing a 6-up lead after 13 holes in a 2-up loss to Tiger Woods in the 1994 U.S. Amateur final, won four of the first six holes and was 5 under in a bogey-free 29 holes.
'It's been a long journey. One that started 13 years ago,' said Kuehne, who earned a spot in the 2008 Masters. 'I got the job done this time. It doesn't get any better than this. It truly is a dream come true. I thought this day would never come.'
Kuehne, from Irving, Texas, is the older brother of LPGA Tour player Kelli Kuehne and PGA TOUR player Hank Kuehne -- both USGA champions. Kelli Kuehne won the 1995 and 1996 U.S. Women's Amateur titles, and Hank Kuehne won the 1998 U.S. Amateur.
The 26-year-old Whitaker, from Cle Elum, Wash., was making his first appearance in the tournament for players 25 and older.
'He made par after par after par and it was tough to catch him,' the long-hitting Whitaker said. 'It still was an awesome week. To get this far at this level is something I've not done before.'
