MELBOURNE, Australia (AP) -- Serena Williams got on and off court as quickly as she could in the scorching heat, registering yet another record with match win No. 61 at the Australian Open as she advanced to the fourth round with a 6-3, 6-3 victory over Daniela Hantuchova.
The five-time Australian Open champion later withdrew from the doubles, avoiding any extra exposure to the blazing sun during the once-in-a-century heat wave that was gripping Melbourne for a fourth straight day.
Two-time finalist Li Na, the major threat to top-ranked Williams in the top half of the women's draw, had to save a match point before coming back to beat No. 26-seeded Lucie Safarova 1-6, 7-6 (2), 6-3 in 2 hours, 37 minutes.
No. 9 Angelique Kerber advanced earlier with a 6-3, 6-4 win over American Alison Riske. Kerber will next play No. 28 Flavia Pennetta, who advanced 6-1, 7-5 over Mona Barthel of Germany.
On the men's side, third-seeded David Ferrer advanced to the fourth round for a 10th consecutive Grand Slam when he beat No. 29 Jeremy Chardy 6-2, 7-6 (5), 6-2. The French Open finalists will next play Florian Mayer, who beat No. 20 Jerzy Janowicz 7-5, 6-2, 6-2.
PARADISE VALLEY, Ariz. (AP) - Ever since the game was invented, before television or even radio existed, baseball counted on the eyes and ears of umpires on the field. Starting this season, many key decisions will be made in a studio far away.
Major League Baseball vaulted into the 21st century of technology, approving a huge expansion of instant replay in hopes of eliminating blown calls that riled up players, managers and fans.
Acknowledging the human element had been overtaken in an era when everyone except the umps could see several views over and over in slow-motion, owners and players and umpires OKed the new system.
Now each manager will be allowed to challenge at least one call per game. If he's right, he gets another challenge. After the seventh inning, a crew chief can request a review on his own if the manager has used his challenges.
NEW YORK (AP) - Tampa Bay left-hander David Price got a big deal, a $14 million, one-year contract. That will be just a small fraction of the mega-contract Clayton Kershaw and the Los Angeles Dodgers are likely to finalize Friday on one of the busiest days of baseball's offseason calendar.
Price, the 2012 AL Cy Young Award winner, agreed to the biggest single-season salary in Rays history. The three-time All-Star, eligible for free agency after the 2015 season, hopes he remains with the budget-minded franchise.
New Oakland closer Jim Johnson, acquired from Baltimore last month, agreed to a $10 million, one-year deal with the Athletics, who also struck a $2.3 million deal with catcher John Jaso. Johnson's 50 saves tied for the big league lead last year, when he was 3-8 with a 2.94 ERA.
Others who agreed included Philadelphia right-hander Kyle Kendrick ($7,675,000), Mets first baseman Ike Davis ($3.5 million), Colorado right-hander Wilton Lopez ($2.2 million), Cincinnati outfielder Chris Heisey ($1.76 million), Kansas City left-hander Tim Collins ($1,362,500) and Yankees catcher Francisco Cervelli ($700,000).
LA QUINTA, Calif. (AP) - Patrick Reed went low in perfect scoring and weather conditions at the Humana Challenge. He wasn't alone.
Reed ran off five straight birdies in the middle of his round on PGA West's Arnold Palmer Private Course and finished with a bogey-free 9-under 63.
Ryan Palmer, Justin Hicks, Daniel Summerhays and Charley Hoffman shot 64. Palmer played the Palmer course, Hicks and Summerhays opened on the Jack Nicklaus Private Course, and Hoffman, the 2007 winner, was at La Quinta Country Club.
MAMMOTH LAKES, Calif. (AP) - Shaun White earned his spot in the Olympics - winner of Thursday's second slopestyle qualifying event despite a nasty, face-first fall in the first contest that almost caused him to scrub the whole day.
White strung together three straight dazzling jumps to score a 95.2, then sat out his second run but got the win when none of the other 12 competitors could do better.
The victory made White the top American in two of the four qualifiers and guaranteed a spot on the U.S. Olympic team.
BOSTON (AP) - American goalie Jesse Vetter will have to go to the Olympics without a quote from the U.S. Constitution on her mask.
Vetter's original design included a reference from the preamble to the Constitution, including the iconic script of the opening words, ''We the People.'' But International Olympic Committee rules ban any ''form of publicity or propaganda, commercial or otherwise,'' on uniforms.
An Arkansas State football player and his stepfather were shot to death during a home invasion robbery in Jackson, Tenn., with the athlete apparently trying to protect his parents from their attackers, police said.
Markel Owens, a 21-year-old junior defensive lineman for the Red Wolves, was fatally shot along with Johnny Shivers, 36, during the robbery at a duplex on Wednesday night. Shivers died at the scene, while Owens was pronounced dead after being taken to Jackson-Madison County General Hospital.
MEXICO CITY (AP) - Jose Sulaiman, the longtime head of the World Boxing Council who promoted renowned fighters and introduced rules to protect boxers, died Thursday. He was 82.
Sulaiman's son, Mauricio Sulaiman, said the man who many say raised the profile of the sport in his four-decade leadership at the Mexico-based council died at a hospital in Los Angeles. He had been hospitalized at the University of California, Los Angeles Medical Center for months for a heart condition.
The WBC confirmed his death, calling him the ''father of boxing.'' Sulaiman was a member of boxing's Hall of Fame since 2006.
