Richard Gasquet makes a winning return after being sidelined with a back/rib injury since Queen’s, defeating Farrukh Dustov 6-3, 6-4.

STANFORD, California (AP)—Third-seeded Agnieszka Radwanska of Poland needed three sets to beat South Africa’s Chanelle Scheepers 7-5, 4-6, 6-3 in the first round of the Bank of the West Classic on Monday.

The 11th-ranked Radwanska hit both of her aces in the third set and won both of her break points. Radwanska, who reached the semifinals at Dubai and Indian Wells, and the fourth round at Wimbledon, has won four of her last five matches.

Scheepers, ranked 91st, reached the fourth round at the French Open as a qualifier and made her debut in the top 100 on June 7.

In other first round matches, Olga Govortsova of Belarus defeated Russia’s Alla Kudryavtsena, 6-1, 6-1 and Dominika Cibulkova of the Czech Republic downed American Hilary Barte, 6-2, 6-2.

LOS ANGELES (AP)—Ernests Gulbis of Latvia and Germany’s Rainer Schuettler won their opening matches in the Farmers Classic tennis tournament on Monday.

Gulbis, at 21 the youngest player in the 28-man field, was a 7-5, 7-5 winner over 22-year-old Lukas Lacko of Slovakia, and Schuettler, at 34 the oldest player in the event, was leading No. 7 seed Horacio Zeballos, 6-3, 3-0, when the Argentine retired with a left shoulder injury.

They were joined in the second round by No. 6 seed Janko Tipsarevic of Serbia, who downed Colombian Santiago Giraldo, 6-1, 6-0.

Gulbis was playing for the first time since injuring a right hamstring muscle at the French Open on May 23, and the No. 5 seed said: “I didn’t care how I play, I just wanted to win, whatever the score, whatever the match (quality), ugly tennis or whatever, to get some wins going.

“The match was really ugly to watch. I didn’t hit too many clean shots. I was running and putting the ball back, but the only thing I did well was serving. In cases like this it’s win, whatever it takes. You push, you run, you fight, do whatever.”

Gulbis, who won his first ATP Tour title at Delray Beach, Florida earlier this year, is a potential opponent for top-seed Andy Murray in the quarterfinals.

Murray, who’s No. 4 in the world, is a wild-card replacement for second-ranked Novak Djokovic, who withdrew for personal reasons. The other top singles seeds with first round byes in this $619,500 event are 2009 champion Sam Querrey of the United States, No. 3 Marcos Baghdatis of Cyprus and No. 4 Feliciano Lopez of Spain.

In doubles, top seeds Bob and Mike Bryan of the United States will be seeking their sixth title here. If successful, they will overtake retired Australian stars Mark Woodforde and Todd Woodbridge for the most championships in the Open era. Both teams have 61.

ISTANBUL (AP)—Defending champion Vera Dushevina struggled against Petra Martic before rallying for a 2-6, 7-5, 6-3 win in the first round of the Istanbul Cup.

Dushevina earned her first WTA Tour title in Istanbul last year but was broken seven times against her Croatian opponent Monday.

Sixth-seeded Andrea Petkovic easily advanced by beating Pemra Ozgen 6-2, 6-1, while No. 4 Yaroslava Shvedova lost 6-4, 7-6 (5) to Stefanie Voegele.

French Open champion and top-seeded Francesca Schiavone led Anne Keothavong 4-0 when their match was suspended because of rain.

MIAMI (AP)—With his ranking on the decline, Roger Federer is working with coach Paul Annacone on a trial basis.

Annacone, an American, is the former coach of Pete Sampras. He also coached Marat Safin and Tim Henman, and is now the head coach of men’s tennis for Britain’s Lawn Tennis Association.

“I’ve been looking to add someone to my team, and I’ve decided to spend some days with Paul Annacone,” Federer said on his website Monday. “As Paul winds down his responsibilities working for the Lawn Tennis Association, we will explore our relationship through this test period. Paul will work alongside my existing team, and I am excited to learn from his experiences.”

In the past two months Federer has slipped to No. 3 in the ATP rankings, the first time since November 2003 he’s been that low. He trails No. 1 Rafael Nadal and No. 2 Novak Djokovic.

Federer has worked with coaches Darren Cahill, Jose Higueras and Tony Roche, but has also gone without a coach for extended stretches.

He’s scheduled to play his first tournament since Wimbledon beginning Aug. 9 in Toronto. He plans to play in Cincinnati the following week before heading to the U.S. Open, and may be accompanied by Annacone.

“They will take the necessary time to see if the relationship can work,” Federer’s agent, Tony Godsick, said in an e-mail. “I would assume that Paul, if he can work it in with his remaining responsibilities and schedule with the LTA, will join Roger for some of his upcoming summer hard court events in North America.”

Federer’s most recent title came in January at the Australian Open, his 16th Grand Slam championship. His record streak of reaching the semifinals at 23 consecutive major tournaments ended when he lost in the quarterfinals at the French Open.

At Wimbledon, he also lost in the quarterfinals following seven consecutive appearances in the final.

Federer topped the rankings earlier this year but was overtaken by Nadal after the French Open. That left Federer one week shy of tying Sampras’ career record of 286 total weeks at No. 1.

Serbia will host the Czech Republic on hard courts in Belgrade for the Davis Cup semifinals in September. France will host Argentina in Lyon, also on hardcourts.

Blake Strode has won a wild card into U.S. Open qualifying by defeating Cecil Mamiit 4-6, 6-4, 7-6 (1).
