Mike McCullough won his first Senior PGA Tour title, closing with a 4-under-par 68 for a one-stroke victory in the Mexico Senior Classic.
McCullough, 55, won for the first time in 612 PGA Tour-sanctioned events -- 401 on the PGA Tour, 178 on the senior tour, and 33 on the Nike/Buy.com Tour.
"I made key putts when I had to," he said. "I've been working hard on my game lately. I've been close a couple of times."
McCullough, who earned $225,000, had a 12-under 204 total on the Las Vista Course. Jim Colbert, coming off a second-round 62, shot a 69 to tie for second with Bob Eastwood (69).
In Singapore, Fiji's Vijay Singh won his second straight tournament, finishing with a 3-under 68 for a two-stroke victory in the Singapore Masters.
Singh, the Malaysian Open winner last week, had a 21-under 263 total. England's Warren Bennett shot a 68 to finish second.
