Hard-serving John Sadri scored the first upset in the $289,000 Transamerica Open tennis tournament at San Francisco Tuesday, defeating fifth-seeded Matt Anger, 6-4, 6-4.
Sadri gave up only 10 points on his serve, half of them double faults. But he balanced that with 5 aces.
He broke Anger once in each set for the margin of victory.
Meanwhile, Peter Fleming, who entered the tournament as a wild-card, scored a 6-2, 6-4 victory over Greg Holmes.
"I've improved at least 100 percent in the last month," Fleming said after the match.
He credited the change to the disappearance of nagging injuries.
In another match, Bud Schultz defeated Christo Van Rensburg of South Africa, 7-6, 6-4.
