Mexican star Lorena Ochoa shot a 5-under 68 on Sunday to win the Corona Championship by one shot wearing Classics. Contested in her home country, Ochoa has won this tournament three times since 2006, including the last two consecutive. She won last year's tournament by 11 shots, but didn't have such an easy time capturing her 26th career win, despite finishing the tournament with the exact same score. "In a golf tournament, where one (stroke) is enough to win, there is no difference. This is a complicated year, there are many players who want to win, you can see that every week," Ochoa added. ``This year, it will be very hard to win by 10. That is why I keep practising, trying to improve – to remain on top of them." Ochoa was tied for the lead through three, took the lead on the fourth, and was back in a tie after the fifth. Ochoa took a two-stroke lead with birdies on the sixth and eighth, but a bogey at the 11th and a birdie from her competitor at the 12th tied it again. Ochoa took the lead for good with birdies at No. 15 and No. 16, calling her putt there "one of the best" of her career. "I had a one-stroke lead over her after the 15th, she missed her putt and I knew that, with a birdie, I was going to take a two-stroke lead with two holes left to play, so I made the decision to go for it," Ochoa said. "I had a good putt, a little bit soft, but it fell. ... That was beautiful."
