Twenty-third seed Clancy Shields pulled the biggest upset of the tournament on a soggy Tuesday when he overwhelmed the seventh seed Donald Young 3-6, 6-4, 6-0 in the fourth round of 18s singles.

"Neither of us played well," Shields said, "but during the rain delay, I told myself to keep the ball in play."

Though play resumed less than a half hour later, the rain washed away Young's momentum, and Shields extinguished any chance Young had to turn the match around. Unlike Young, who celebrated his 15th birthday in July and turned professional while still 14, Shields has no plans to do the same.

"No," Shields, 17, laughed, "not unless something real great happens this year."

Young was the only top 16 seed to lose in 18s singles play on Tuesday.

In 16 singles, only one unseeded player remains, Michael McClune of Irvine CA, who defeated 10th seed Kellen Damico, 6-3, 1-6,
6-2. Shan Sondhu (8), lost to William Guzick (28), 4-6, 7-6 (5), 6-3.

18 doubles fourth round matches were rained out, as play at the Stowe and Western courts was restarted at least seven times during the afternoon due to intermittent showers.

In 16 doubles fourth round--finished inside at WMU West Hills Athletic Club--the only upset saw the 16th seeded team of Kenneth McGovern and Bradley Mixson rally to take out the fifth seeds, Shan Sondhu and Michael Sroczynski, 3-6, 6-3, 6-4.
