Kucher carves out four-shot lead

Matt Kuchar had another rough hole and enough birdies to atone for it Saturday, posting a 6-under 65 to open a four-shot lead in the Mayakoba Golf Classic. Kuchar hit a wild drive to the right into mangroves on the par-4 14th and had to get up-anddown to salvage a bogey. That was the only big mistake for Kuchar, who is going after his first PGA Tour title in more than four years.
