KEY BISCAYNE, Fla. (AP) -- Serena Williams has broken the Key Biscayne women's record for most titles, and Maria Sharapova has set a new standard for futility in finals.
Williams swept the last 10 games and earned a record sixth title Saturday by rallying past Sharapova, 4-6, 6-3, 6-0, at the Sony Open.
Sharapova completed a career Grand Slam by winning the French Open last year, but she's now 0-5 in Key Biscayne finals. She played nearly flawless tennis for the first hour, but then began to miss with her serve. Williams dominated rallies with her power down the stretch.
At 31, the No. 1-ranked Williams became the oldest female champion at Key Biscayne. She won the tournament for the first time since 2008 and surpassed Steffi Graf, a five-time champion.
