Mayo, 12, defeated No. 7 Benjamin Kittay of Potomac, Md., 6-3, 6-2 on Saturday to set up a showdown with No. 1 Xiaofei Wang of China. Wang beat Martin Damm, a 6-foot-2 left-hander from Bradenton, Fla., 7-5, 6-1.
Damm's father, a Czech also named Martin, reached career highs of No. 42 in singles in 1997 and No. 5 in doubles in 2007. He won the men's doubles title in the 2006 U.S. Open with Leander Paes of India.
Mayo, who ousted No. 9 Ashton Cross of Canada in the third round, has not lost a set in four matches. Wang has dropped one match.
In the fourth round of the girls 14s, No. 4 seed Katie Volynets of Walnut Creek in the San Francisco Bay Area lost to No. 9 Oana Corneanu of Romania 6-1, 7-5.
Volynets, whose parents emigrated from Ukraine 19 years ago, will turn 14 on Dec. 31. Corneanu, a hard-hitting left-hander, celebrated her 14th birthday on June 25.
