In brief: Murray to face Del Potro for Rogers Cup

Tennis: Britain’s Andy Murray defeated Jo-Wilfried Tsonga of France and Juan Martin Del Potro ousted Andy Roddick on Saturday in the semifinals of the Rogers Cup at Montreal.

With his win, Murray will vault past Spain’s Rafael Nadal into a career-high second in ATP rankings behind No. 1 Roger Federer of Switzerland when the next rankings are released Monday. Nadal, returning from a knee injury, lost in the quarterfinals Friday night.

Murray ousted the seventh-seeded Tsonga 6-4, 7-6 (8).

Del Potro beat Roddick 4-6, 6-2, 7-5. He also defeated the fifth-seeded American in a third-set tiebreaker in the final of a tournament in Washington last Sunday.

The two held service at 5-5 in the third, when Roddick went down 30-40 and then double-faulted. The 2003 Rogers Cup champion slammed his racket down on the court and the sixth-seeded Del Potro then served out the match.

•Safina beats Pennetta to reach Cincy final: Dinara Safina needed only 56 minutes to eliminate Italy’s Flavia Pennetta 6-2, 6-0 in the semifinals of the Cincinnati Open. The world’s top-ranked woman will play Serbia’s Jelena Jankovic for the championship of the $2 million Western & Southern Financial Group Women’s Open at Mason, Ohio.

Safina reached her eighth final in 14 tournaments this year, ending Pennetta’s winning streak at 15.

Jankovic’s ragged 7-6, (2), 0-6, 7-6 (6) win over Elena Dementieva took 2 hours, 46 minutes in the evening.

The fifth-seeded Jankovic blew three match points in the third set, setting up the tiebreaker, then fell behind 6-2 before pulling it out. There were 13 service breaks and 25 double faults in the match.

Keselowski takes Nationwide race

Auto Racing: Brad Keselowski swooped past Brian Vickers and Kyle Busch to take the lead in the final turn, then held on to win the Nationwide series race at Michigan International Speedway in Brooklyn, Mich.

Keselowski took two tires on his final pit stop, then took advantage of a furious battle for the lead between Vickers and Busch on the last lap. Vickers finished second and Busch third, and they exchanged some heated words on pit road afterward.

“Brian was doing what he needed to do to win the race, and just kind of got snookered by us in the end,” Keselowski said.

It was a rough afternoon for Carl Edwards, whose hopes of a championship in NASCAR’s second-tier series took a hit when he crashed early.

January scores 17 in Fever’s win

Basketball: Katie Douglas scored 19 points, and the Indiana Fever overcame a 14-point deficit to beat the Detroit Shock 82-59.

Rookie Briann January, a Lewis and Clark graduate, scored a career-high 17 points and Tamika Catchings had 10 points, nine rebounds and four steals for the Fever (19-5).

Shavonte Zellous led Detroit (9-13) with 16 points.

Detroit shot 53 percent in the first half, but just 29 percent in the second. Indiana scored 45 points off Detroit’s 24 turnovers to win their 12th straight at home.

Armstrong ends Wiens’ reign

Miscellany: Lance Armstrong won the Leadville 100 in a record time, finishing the nation’s highest-altitude mountain bike race in Leadville, Colo., on a flat tire.

Armstrong dethroned six-time defending champion Dave Wiens, winning in 6 hours, 28 minutes, 50 seconds. Wiens had set the previous record of 6:45:45.

He had beaten the seven-time Tour de France winner by nearly two minutes last year. But that was before Armstrong began training in earnest for his return to the Tour this year.

She finished with 117.55 points to beat out Hong by 0.3 and Bross by 0.95.
