(CNN) -- World No. 4 Andy Murray will seek to win his first tennis title of 2010 when he faces defending champion Sam Querrey in Sunday's final of the Farmers Classic in Los Angeles.
The British star, who was made top seed on a wild-card entry after world No. 2 Novak Djokovic pulled out, progressed to his first final since January's Australian Open despite another up-and-down performance in the ATP Tour event.
The 23-year-old, playing his first tournament since reaching the Wimbledon semifinals last month, defeated Spain's Feliciano Lopez 6-0 1-6 6-4 on Saturday.
He needed four match-points before finally triumphing, but has a 4-0 career record over the 22-year-old Querrey.
"When you haven't played much over the last month you're not going to be particularly consistent," Murray told the ATP Tour website.
"I played some really good stuff, I played some bad stuff, and just did enough to win.
"It was a pretty late decision to come here, so obviously I wanted to come and try to win this event, but you have to have realistic expectations. I wasn't expecting to play my best tennis, but try and play as many matches as possible.
"It's a lot better playing tournaments of this caliber than practicing with my friends in Miami, obviously. I'm glad I came and I played some good tennis, and definitely it'll help me for Toronto and Cincinnati."
Querrey, the only player to win on three different surfaces this season, came back from 5-1 down in the second-set tie-breaker to beat sixth seed Janko Tipsarevic 6-7 (3-7) 7-6 (7-5) 6-4.
"You got to make the guys earn it. That's what I was trying to do, and it's not over till that last point," the American said after his third three-setter of the tournament.
"I'm going to have to take some chances. I'm going to try to go out there with nothing to lose, and hopefully play well. I hope I can serve well again. You have to serve well against him because he returns so well."
It will be the first time since Pete Sampras' win over Andre Agassi in 1999 that the top two seeds have met in the final.
The Bryan brothers Mike and Bob will seek to win a record 62nd doubles title in their 100th top-level final, with the Americans to face Eric Butorac and Jean-Julien Rojer.
In Switzerland, world No. 18 Nicolas Almagro won his seventh career title at the Gastaad Open, beating France's Richard Gasquet in Sunday's final of the clay-court event.
Meanwhile, Maria Sharapova will seek to win her third title this season in Sunday's final of the Bank of the West Classic against Victoria Azarenka in Stanford.
The Russian fifth seed, who triumphed in Memphis and Strasbourg before losing in the Birmingham final, defeated No. 3 Agnieszka Radwanska 1-6 6-2 6-2 on Saturday night despite losing her serve three times out of four in the first set.
The 23-year-old was also broken once in each of the next two sets before extending her career record over the Pole to 5-1.
"I was all over the map for a little while. I cut down on the unforced errors and little by little I came back," she told the WTA Tour website.
"She wins a lot of her matches by wearing her opponents down, getting a lot of balls back. You have to be ready for the next shot to come back, and every shot is a new one."
Eighth seed Azarenka continued her dominance over top seed Sam Stosur, winning 6-2 6-3 on her 21st birthday to extend her run of not dropping a set against the French Open runner-up in their fourth meeting.
"I served well, played very well on the return and was solid from the baseline," the Belarusian said ahead of her third final this year, having lost the other two.
"Sam's an amazing player. She has had great results this year and it gives me even more confidence I can beat her when she's in good form. It's also good to win on my birthday!"
Sharapova has won the last two of their three meetings, both also on hard-court surfaces last year.
In Turkey, teenager Anastasia Pavlyuchenkova rallied to win her second career title on Sunday, beating fellow Russian Elena Vesnina in the final of the Istanbul Cup.
The 19-year-old won 5-7 7-5 6-4 after losing nine games in a row to trail 4-0 in the second set.
Vesnina suffered the third final defeat of her career on her 24th birthday.
