Second-seeded Tom Matthews defeated top-ranked Raheil Qureshi, 3-1, in the men's open division of the Snauwaert Summer Grand-Prix Series at the Washington Squash Racquets Club yesterday.

In the women's open final, Cassie Fisher beat Mary McGuirk, 3-1.

Qureshi attributed his loss to his 3-1 semifinal victory over professional Neil Vohr that took 1 hour 20 minutes earlier in the day.

"I had a very hard semifinal match," Qureshi said. "I became very tired and never recovered. Tom did not have a hard semifinal match, and he was relatively fresher."

Matthews, 24, the teaching professional at the Capitol Hill Squash Club, easily defeated Will Carlin, 3-0, in his semifinal. "Whenever I play Raheil we have a very brutal match," he said. "And it seemed like I endured longer. Tournaments turn into endurance matches."

Matthews won the first of the Series in June, beating Qureshi, 3-1, for the second consecutive time. He will be top seeded in the last of the series in August; Qureshi will be No. 2.

In the men's B division, Steve Rawls beat Don Berk, 3-0; Tad Louie won the C division, defeating Alan Goldberg, 3-0; in the D/novice level, James Campbell beat Dan Sherman 3-1, and Pedro Kuczynski won the men's 40-plus division, 3-0, over Malcolm Jensen.

In the women's B/C division, Valerie Hopkins beat Dietra Sarris, 3-2.
