seed Maria Sharapova breezed to a 6-2, 6-1 victory over Swedish qualifier Sofia Arvidsson to easily win the Memphis Championships women's title Saturday. The dominant Russian did not drop a set during the tournament as she won her 21st career title. “I feel great. I came here for matches - I got five and I got the win, so it was a good week,” Sharapova told reporters. “I served and returned well, two things that are very important indoors.” Arvidsson, who won at Memphis in 2006, lost nine successive games from 2-2 in the first set. In the men's draw, US Davis Cup teammates Sam Querrey and John Isner set up an all-American showdown with contrasting semifinal victories. Eighth seed Querrey held off Latvian Ernests Gulbis 6-3, 6-4 after the sixth-seeded Isner beat German Philipp Petzschner 7-5, 4-6, 6-3. The pair will face off Sunday before teaming up to represent the United States in a Davis Cup World Group tie against Serbia in Belgrade on March 5-7. Federer withdraws Roger Federer has been forced to withdraw from the Dubai championships starting Monday because of a lung infection, the ATP said on its website Sunday. The ATP said the world No. 1 was now expected to return to action for the first time since winning the Australian Open at the World Tour Masters tournament in Indian Wells starting on March 11. Swiss Federer, a four-time former champion in Dubai, will be replaced in the draw by Spaniard Tommy Robredo. Llodra wins Marseille In France, Michael Llodra cruised to his fourth career title when he beat fellow Frenchman and doubles partner Julien Benneteau 6-3, 6-4 in the Marseille Open final Sunday. Both men were then due to contest the doubles final against Austrian Julian Knowle and Swede Robert Lindstedt. Llodra, who lost to Jo-Wilfried Tsonga in last year's final, never looked in danger on his own serve as he fired 14 aces, including one on his first match point. Ferrero-Ferrer final In Argentina, Juan Carlos Ferrero and David Ferrer won their semifinals Saturday to set up an all-Spanish final of the Copa Telmex. Second-seeded Ferrero reached his second straight final when he downed former champion Juan Monaco of Argentina 6-2, 7-6 (7), while top-seeded Ferrer overpowered countryman Albert Montanes 6-1, 6-1. Ferrero won his 13th career title last weekend at the Brazil Open, and Saturday's semifinal victory was his ninth straight. “Did I expect to reach the final here?” Ferrero said, responding to a question. “When I started the South American tour in Brazil I found some problems having to play on clay, but I improved.”
