NEW YORK — The Latest on the U.S. Open (all times local):
9 p.m.
Serena Williams has won the first set of her U.S. Open quarterfinal against sister Venus as she seeks to complete the first Grand Slam since 1988.
The younger Williams took the set 6-2 in 33 minutes Tuesday night in front of a celebrity-filled crowd at Arthur Ashe Stadium.
Unlike some previous meetings when the awkwardness of the moment affected the performances of both, each was sharp at the start Tuesday. Venus kept up her strong play from the last two rounds.
