Danville, CA (My Sportsbook) - Sweden's Sophie Gustafson broke free of world No. 1 Lorena Ochoa to win the CVS/pharmacy LPGA Challenge on Sunday, closing with a four-under 68 in the final round.

Gustafson, who shared the third-round lead with Ochoa, captured her fifth tour victory at 20-under 268 -- four shots in front of the Mexican star, who played alongside her in the final group.

Ochoa, in position to finally snap a five-month losing streak, only managed an even-par 72 on the Blackhawk course as she finished at 16-under 272.

Amy Yang (66) and Sun Young Yoo (68) shared third place at 14-under 274.

While Gustafson enjoyed her first LPGA win since the 2003 Samsung World Championship, Ochoa endured yet another disappointing Sunday as she looked to finally break free from her winless slump.

Among the top 18 players on the final leaderboard, only Ochoa and Leta Lindley failed to break par.

It got way from Ochoa early on.

The long-hitting Gustafson collected key birdies at the first and third holes, then made an eagle at the par-five fifth as she built a three-shot lead over Ochoa.

Ochoa, meanwhile, didn't collect her first birdie until No. 5. She later went bogey-birdie on the last two holes of the front nine and was two strokes behind around the turn.

Gustafson held her at bay with a steady back nine that included a 10-foot birdie at the 13th, which restored her three-shot lead. She made a bogey at the 18th, but so did Ochoa.

The closing bogey for Ochoa put her at one-over par for the back nine. It was her fifth top-10 finish since she won the Corona Championship in her native Mexico in April.

A dominant force on the LPGA Tour since she took over the No. 1 ranking a couple of seasons ago, Ochoa stands just eighth on the money list this year. She has won only twice this season after collecting 21 combined victories in the previous three.
