LONDON (AP) — Six-time champion Roger Federer rallied past Juan Martin del Potro 4-6, 7-6 (2), 7-5 Saturday to reach the semifinals of the ATP World Tour Finals for an 11th time.
Federer will face top-ranked Rafael Nadal today, and Novak Djokovic will take on newcomer Stanislas Wawrinka in the other semifinal at the year-end tournament.
Federer and del Potro needed a win in their final round-robin match to advance from Group B.
Only once in 12 appearances has Federer failed to reach the final four. The 17-time Grand Slam winner has struggled this season, and the event featuring the top eight players is his last chance to win a big title in 2013.
Busch wins Nationwide race
AVONDALE, Ariz. (AP) — Kyle Busch raced to his 12th NASCAR Nationwide Series victory of the year and Austin Dillon maintained his hold on the championship lead with a third-place finish at Phoenix International Raceway.
Justin Allgaier passed Dillon on the last lap Saturday for second place, and it cost Dillon a point in the standings. Dillon takes an eight-point lead over Sam Hornish Jr. into next week’s season finale at Homestead. Hornish finished fifth.
Kirk, Baird tied for lead
ST. SIMONS ISLAND, Ga. (AP) — Chris Kirk and Briny Baird each made birdie on the 18th hole Saturday to separate themselves from the pack at Sea Island.
But not by much.
Kirk holed a 25-foot putt for a 2-under 68. Baird followed him with an 8-foot birdie putt for a 67. They were tied for the lead going into the last round, a shot ahead of Kevin Stadler, Brian Gay and John Senden. Twelve players were separated by four shots going into today, a group that includes Matt Kuchar and Webb Simpson.
Baird is playing his 365th event on the PGA Tour without ever winning. The top eight players on the leaderboard have combined for seven career wins, and that includes Gay’s four wins.
The winner today gets an exemption to the Masters.
• GOLD COAST, Australia (AP) — Adam Scott shot an even-par 71 on Saturday at wind-swept Royal Pines to open a three-stroke lead in the Australian PGA.
The tournament is the first of four straight in Australia for Scott, playing at home for the first time since winning the Masters. He had a 10-under 203 total.
American Rickie Fowler and Australian David McKenzie were tied for second. Fowler had a 71, and will play alongside Scott in the final twosome Sunday. McKenzie shot 72.
• SHIMA, Japan (AP) — Japan’s Mamiko Higa, Yuki Ichinose and Shiho Oyama shared the second-round lead Saturday in the Mizuno Classic, the final tournament in the LPGA Tour’s five-event Asian swing.
Higa and Ichinose shot 6-under 66 to match Oyama at 8 under at Kintetsu Kashikojima in the event also sanctioned by the Japan LPGA Tour. Oyama, the first-round leader, had her second straight 68.
American Brittany Lincicome and Japan’s Asako Fujimoto were a stroke back. Lincicome had a 68, and Fujimoto shot 67.
Defending champion Stacy Lewis was 5 under after a 68. The American overcame a seven-stroke deficit in the final round last year, birdieing the last three holes for a 64 and a one-shot victory.
She’s the top-ranked player in the field at No. 3 and has three victories this year.
