Sophie Gustafson won on the LPGA Tour for the first time in six years, cruising to a four-stroke victory Sunday over top-ranked Lorena Ochoa in the CVS/pharmacy LPGA Challenge. The 35-year-old Swede shot a 4-under 68 at Blackhawk Country Club and finished at 20-under 268 to win her first LPGA Tour title since the 2003 Samsung World Championship. She earned $165,000 for her fifth career tour victory. Ochoa shot an even-par 72 to finish at 16 under. She's winless in 11 starts since taking the Corona Championship in her native Mexico in late April. She has only two victories in 17 events this year after winning 21 times in the previous three years. Amy Yang (66) and Sun Young Yoo (68) tied for third at 14 under. Ochoa could sense it was Gustafson's day from the start Sunday. Last week at the Samsung, Ochoa edged Gustafson by three strokes to tie for fourth. “I have felt good but I haven't gotten it done,” Gustafson said of her past events. “I felt good about my game, but the thing about my game is it can come and go. I don't know what to expect.” Ochoa missed chances all over the course. “I thought maybe the back nine was mine,” Ochoa said. “I gave myself birdie chances on 10, 12, 13 and 14 and none of them dropped. I would have had some momentum and put some pressure on Sophie.” Gustafson missed a chance to pick up a stroke on No. 8, a tricky 360-yard par 4. Ochoa's tee shot landed far to the right near the gallery, across the cart path about 6 inches from an iron fence bordering a house. Upon seeing her lie, Ochoa slapped her leg in frustration. Opting against a drop and after a discussion with her caddie, Ochoa's second shot required a short back swing because of the fence. Her choked-up 5-iron shot ricocheted off a plastic irrigation cover 15 feet away and landed in the deep rough parallel to her previous shot. She slammed the club head into the ground. “Sometimes you also have to get a few good breaks and it just didn't happen for me,” Ochoa said. “That's the way it is.”
