Serena Williams won her eighth Key Biscayne title Saturday and remained unbeaten this year by drubbing Carla Suarez Navarro 6-2, 6-0 in the final of the Miami Open.
Williams became the fourth woman to win the same WTA event at least eight times. Martina Navratilova won Chicago 12 times, the most titles by a woman at any tournament.
Navratilova was on hand to present the top-ranked Williams with her latest trophy.
Williams claimed her second title this year. She won her 19th Grand Slam championship at the Australian Open in January and has now won 12 consecutive finals.
Williams improved to 18-0 this year. She withdrew before the Indian Wells semifinal last month with a knee injury but quickly recovered.
The top-seeded American team of Mike and Bob Bryan captured their fourth men's doubles title in Miami by downing second-seeded defending Wimbledon champs Jack Sock and Vasek Pospisil 6-3, 1-6, (10-8).
In men's singles, top-seeded Novak Djokovic is within one win of his fifth Key Biscayne title. He will meet Andy Murray on Sunday.
A Derby favorite? Try Dortmund
Call it Selection Saturday — three important prep races run in a stretch of 90 minutes to determine which horses had a realistic chance to capture the 140th running of the Kentucky Derby on May 2. When it was over, there was little doubt about the overwhelming favorite at this moment.
His name is Dortmund, a strapping and fast colt that decimated five rivals here in the Santa Anita Derby to remain undefeated.
Dortmund, now 6-for-6, overcame a stumble out of the gate to lead every step of the way in an emphatic 4 ¼-length victory.
He finished strong, covering the 1 ⅛-mile distance in 1:48.73. His rider, Martin Garcia, looked like he was out for a pleasure ride as Dortmund turned for home. His whip was idle and blowing in the wind like an antenna.
"I didn't do anything," Garcia said. "He just dragged me around there."
Dortmund shares a trainer, Bob Baffert, and a barn with American Pharaoh and One Lucky Dane.
American Pharaoh was last year's 2-year-old champion and is the favorite to win the Arkansas Derby next week at Oaklawn Park. Lucky Dane finished second Saturday and earned a trip to the Kentucky Derby as well.
Also in the Derby field will be Frosted, who won the Wood Memorial at Aqueduct Racetrack — going the 1 ⅛-mile in 1:50.31. He had previously shown more potential than results, finishing fourth in the Fountain of Youth at Gulfstream Park. Afterward, his trainer, Kiaran McLaughlin, had throat surgery performed on the horse to help with his airways.
"We know he has a ton of ability, and the last race really made us scratch our heads, asking why he would go to the lead and throw his head up and stop," McLaughlin said. "We did everything we could to change everything we possibly could."
In the Bluegrass Stakes in Kentucky, Carpe Diem established himself the class of the East Coast-based horses. He has now won four of his five races and impressed his jockey, John Velazquez. He took command at the top of the stretch and rushed on for a 3-length victory.
"There wasn't much speed in the race," Velazquez said. "It was a nice slow pace, and I didn't want to fight him very much. Down the Lane, I asked him and he responded right away."
U.S. shuts out New Zealand in St. Louis
Defenders Meghan Klingenberg, Lori Chalupny and Julie Johnston scored in the United States' dominant 4-0 exhibition victory over New Zealand before 35,817 at Busch Stadium in St. Louis.
"It's not just about defending, it's also about adding to the attack and being creative out there," Chalupny said. "It's not surprising, actually, it's kind of the way we play."
Klingenberg scored early before the U.S. busted the game wide open after the half when Chalupny, Johnston and midfielder Morgan Brian scored in a span of five minutes in the World Cup warmup.
The U.S. has three more exhibitions before the World Cup.
