Two-time champion Serena Williams was a second-round winner, while No. 2 seed Agnieszka Radwanska was sent packing Wednesday at the Bank of the West Classic, a U.S. Open Series tennis event.
Playing her first tennis since a stunning third-round loss at Wimbledon last month, Williams beat Karolina Pliskova by a 7-5, 6-2 score on the hardcourts at Taube Family Tennis Center.
Williams was the back-to-back titlist here in 2011 and 2012.
