Sports: NASCAR Chase Changes; Serena Loses Down Under; NBA, NHL, PGA

By  | 

CHARLOTTE, N.C. (AP) -- A 16-driver championship field that would be whittled down to create a winner-take-all season finale is among radical changes reportedly being considered by NASCAR.
The Charlotte Observer first reported the possible changes Friday night.
The Observer cited anonymous sources in outlining a Chase field that would kick out the four lowest-ranked drivers after three races. The points would be reset, three more drivers would be kicked out after three more races and the finale would be a winner-take-all for the four remaining drivers.
NASCAR chairman Brian France has repeatedly said he wants to place a greater emphasis on winning. He's said he'd never ruled out tinkering with the Chase for the Sprint Cup championship format in an effort to create the "Game 7 moments" he wants to create.

(AP) -- The NBA's Western Conference teams have dominated the East with regularity this season, but the Indiana Pacers continue to have success in interconference games.
The Pacers are 10-2 against the West and a league-best 32-7 overall following Saturday's 106-92 win over the Los Angeles Clippers. Paul George scored 36 points and Lance Stephenson added 22 points and 12 rebounds to send Indiana to its fourth consecutive win.
The Clippers shot just 39 percent in ending a five-game winning streak.
Indiana's lead in the East remains 3 1/2 games over Miami following the Heat's 104-96 overtime win against Charlotte. LeBron James finished with 34 points and Chris Bosh had 25 as the Heat won their second straight since a three-game skid.
Portland owns a piece of the Western Conference lead after LaMarcus Aldridge contributed 30 points and 12 rebounds to the Trail Blazers' 127-111 win at Dallas. Nicolas Batum (bah-TOOM') scored 21 for the Trail Blazers, while Robin Lopez added 16 points and 12 rebounds to Portland's fifth consecutive win.
The Blazers and San Antonio are 31-9, one game ahead of Oklahoma City.

(AP) -- Dennis Rodman has checked into an undisclosed alcohol rehabilitation center to treat his long-time struggle with alcoholism. That's according to his agent, who declined to say which facility will treat Rodman and how long he will be there.
Rodman recently returned to the United States from his latest trip to North Korea. He later apologized for comments he made in North Korea about a detained American missionary, saying he had been drinking and was under pressure as he organized an exhibition game there.

MELBOURNE, Australia (AP) -- The Australian Open women's quarterfinals will not include Serena Williams.
The top seed suffered her first loss since August, falling 4-6, 6-3, 6-3 to No. 14 Ana Ivanovic (ee-VAH'-noh-vihch). Williams had won her last 25 straight matches and had never lost a set in four previous meetings with Ivanovic. Williams was seeking her 18th Grand Slam title and sixth at Melbourne.
Two-time finalist Li Na has advanced to the quarterfinals for the fourth time in five years.
The fourth-seeded Li broke serve five times and rolled to a 6-2, 6-0 win over No. 22 Ekaterina Makarova. Li fared better than ninth seed Angelique Kerber, who dropped her fourth-round match 6-1, 4-6, 7-5 to Flavia Pennetta. That sets up a quarterfinal meeting between Li and Pennetta.

Ducks nip Blues
(AP) -- The Anaheim Ducks went back to their winning ways on Saturday after falling in Chicago two nights earlier.
Ryan Getzlaf (GETS'-laf) scored the game's first goal and set up Cam Fowler's game-winner while the Ducks were building a 3-0 lead in a 3-2 triumph at St. Louis. Frederik Andersen backstopped Anaheim's 19th victory in 21 goals, turning back 34 shots and blanking the Blues until Barrett Jackman scored midway through the third period.
