2008 & 2010 Women's Senior Player of the Year
Diane was named the 2008 Women's Senior Player of the Year after her winning the U.S. Senior Women's Amateur Championship for the third time. Diane defeated Toni Wiesner, of Texas, 6&5 in the final match at Tulsa Country Club. With this victory, Diane became the sixth woman to win the U.S. Senior Women's Amateur three or more times. She had an impressive 22-1 match record over four years, with a semifinalist finish in 2007.
