Miami  - Russians Maria Sharapova and Nikolay Davydenko both withdrew on Friday from next week's Miami Masters with injuries as the American hard court season moves to its second major event of the month.

Sharapova, who underwent shoulder surgery last October, tried and failed to test her shoulder with doubles last week at Indian Wells, California, losing in the first round with partner Elena Vesnina.

Her return to the WTA now looks to be put back to Rome on clay in May.

Indian Wells, California  - On-fire American Andy Roddick dismissed Novak Djokovic 6-3, 6-2 to send the defending champion out in the quarter-finals of the Indian Wells Masters on Friday.

The 68-minute rout improved Roddick's best start of his career. He stands 23-3 after playing in his fifth quarter from as many events in 2009.

Djokovic, who won Dubai last month but crashed to a pair of Davis Cup defeats a week later in Spain, was humbled in a little over an hour. Roddick ended each set with a break as the Serb lost serve four times.

Indian Wells, California  - Vera Zvonareva followed up on a Grand Slam semi-final with a win into the final of the Indian Wells Masters on Friday, defeating doubles partner Victoria Azarenka 6-3, 6-3.

The fourth-seeded Russian winner took less than 90 minutes to go through in spring heat in the desert. Zvonareva, who reached the Australian Open final four, now owns a
4-0 record over Azarenka and has not lost a set in that series.

Indian Wells, California - The WTA will take a hard financial line with the Williams sisters, who have boycotted the Indian Wells Masters since a booing incident in 2001.

Tour boss Larry Scott says that Venus and Serena will pay the price for their continual absences from the required event. "There will be sanctions despite the personal issues of the Williams sisters," said Scott. "They will pay significant consequences."

Indian Wells, California  - Andy Murray had his difficult moments before managing to snuff the candles on the 30th birthday celebrations of opponent Ivan Ljubicic 7-5,
7-6 (8-6) in the quarter- finals of the Indian Wells Masters on Thursday.
