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 said.

"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 on Sunday before teaming up to represent the United States in a Davis Cup World Group tie against Serbia in Belgrade on March 5-7.

Querrey, who beat top seed and defending champion Andy Roddick in the quarterfinals, broke Gulbis in each set while saving all nine break point opportunities.

"I came up big on the break points," the world No. 31 said. "I think I made a high percentage of first serves on most of them and I just kind of willed out that last game at 5-4." World No. 25 Isner converted three of 11 break points and smashed 13 aces to win his first meeting with Petzschner.

The tall American has a 12-1 record this year, which includes his first ATP tour title at Auckland in January.

"I had some chances early in the second to pull away a little bit, didn't do it," Isner said.

"It went to a third set and I told myself not to get rattled, which I didn't.

I knew that I still had my serve in my pocket - I'm going to hold serve, take my chances on the return game, and I like my chances in the third set no matter who I'm playing.

"I usually play pretty well in the third."

In Buenos Aires, top seed David Ferrer crushed compatriot Albert Montanes 6-1, 6-1 on Saturday and is favorite to beat Juan Carlos Ferrero in an all-Spanish final at the Buenos Aires Open.

The title will remain in Spanish hands after Tommy Robredo's victory at the Buenos Aires Lawn Tennis Club last year and Ferrero will be looking for a second successive crown in South America after winning the Brasil Open last week.

Ferrer's semifinal victory came in his second match of the day. He beat Russian sixth seed Igor Andreev 7-5, 6-2 in their afternoon quarterfinal, postponed due to torrential rain at the claycourt event on Friday.

The world number 19 has a 5-1 record against second seed Ferrero and was in devastating form against Montanes, who only managed to check the former world number four's progress for a few face-saving points at the end of each set.

Montanes had a bye into the semifinals after home favorite David Nalbandian withdrew with a leg muscle tear on Thursday, having won his first two matches in his comeback tournament from hip surgery nine months ago.

"I'm happy to be in my first final of the year (and) happy there are two Valencians in the final," Ferrer said in a courtside interview, referring to his and Ferrero's home province of Valencia.

Former world number one Ferrero, who will be seeking his 14th title, beat Argentine Juan Monaco 6-2, 7-6 in the first semifinal, which was also the home player's second match of the day.

Monaco, the 2007 champion and runner-up last year, had earlier completed a 7-5 6-1 quarterfinal win over fellow Argentine Horacio Zeballos.

Ferrero, the fresher man having played his quarterfinal on Friday before the rainstorm, fought back from 5-2 down in the second set. He relinquished a 5-1 lead in the tiebreak before winning it 9-7 on his third match point
