LONDON (AP) - Serena Williams has started her Wimbledon title defense with a victory over Mandy Minella of Luxembourg, using her dominant serve to win 6-1, 6-3 on Centre Court.
Williams didn't drop a single point on her serve until the start of the second set, when Minella took a 2-0 lead Tuesday after the American double-faulted on break point.
Williams won the next four games to regain control and broke again to wrap up the match.
Williams is looking for her sixth Wimbledon title and improved her career record to 68-8 at the All England Club. She extended her career-best winning streak to 32 matches, which included her second French Open title.
The 92nd-ranked Minella was making her second appearance at Wimbledon, having lost in the first round in 2012.
