INDIAN WELLS, Calif. — Defending champion Juan Martin del Potro has withdrawn from next month’s BNP Paribas Open because of a knee injury.
Del Potro said Wednesday through tournament officials that he’s been advised to rest by his doctors and he hopes to return to action soon. He defeated Roger Federer to win his first Masters 1000 title last year in the Southern California desert.
The fourth-ranked Argentine lost in the quarterfinals of last week’s Delray Beach Open in Florida. It was del Potro’s first tournament since injuring his knee at the Shanghai Masters in October.
Del Potro had already pulled out of this week’s Mexican Open in Acapulco, which he won last year. He also missed the Australian Open in January.
With del Potro’s withdrawal, Taro Daniel of Japan moves into the men’s draw.
The women’s draw already lost two-time winner Maria Sharapova, who withdrew with a shoulder injury.
The tournament runs March 6-17 in Indian Wells.
WIMBLEDON, England (AP) Roger Federer delivered another vintage Centre Court performance to reach a record-extending 17th Wimbledon quarterfinal.
Federer ousted 17th-seeded Matteo Berrettini 6-1, 6-2, 6-2 in a match that only lasted 1 hour, 14 minutes.
The eight-time Wimbledon champion lost only one point on his serve in the first set and didn’t face a break point until he was up 3-0 in the third. He saved that one and went on to serve out the match at love.
The 37-year-old Federer became the oldest man to reach a Grand Slam quarterfinal since Jimmy Connors did it at 39 at the 1991 U.S. Open.
WIMBLEDON, England (AP) Four-time champion Novak Djokovic is into the Wimbledon quarterfinals again after beating Ugo Humbert in straight sets.
Djokovic took advantage of 34 unforced errors to win 6-3, 6-2, 6-2 on No. 1 Court and set up a meeting with David Goffin.
Djokovic, who beat Kevin Anderson in last year’s final, reached his 11th Wimbledon quarterfinal. That puts him level with Boris Becker in fourth place on the all-time list. Roger Federer was trying to reach a record-extending 17th later.
Goffin beat Fernando Verdasco 7-6 (9), 2-6, 6-3, 6-4.
Sam Querrey also advanced after winning an all-American matchup against Tennys Sandgren 6-4, 6-7 (9), 7-6 (3), 7-6 (5).
