PLAYA DEL CARMEN, Mexico — Graeme McDowell ended one of his worst years with one of his best shots. He hit an approach to 3 feet for a birdie on the 18th hole Monday to win the OHL Classic at Mayakoba in a three-man playoff.
McDowell closed with a 66 to finish at 18-under 266 which he thought would be only good enough for second place.
Russell Knox, coming off his first win last week in Shanghai at the HSBC Champions, had a one-shot lead playing the 18th hole until he pulled his tee shot into a bunker, came up short of the green and missed a 12-foot par putt.
Jason Bohn saved par on the final hole to join the playoff.
The playoff lasted one hole thanks to McDowell’s shot, which nearly went in.
The tournament was held over to Monday because of rain on Sunday.
The fourth round was delayed 3 1/2 hours by thunderstorms that left pools of water across El Camaleon Golf Club.
McDowell elected to finish the par-5 13th when the horn sounded to suspend play because of darkness. He made birdie to join Knox at 19-under par.
Knox was still on the 13th hole on Sunday,
It was the first time in 10 years that back-to-back PGA Tour events finished on Monday because of rain. The Sanderson Farms Championship in Mississippi had a marathon finish last Monday because of the weather.
Knox was hoping to become the first player since Camilo Villegas in 2008 to win his first two PGA Tour titles in successive weeks.
McDowell had not had a top 10 since the Dubai Desert Classic in February. He chose to end his European Tour season earlier than usual because of a mediocre season, and because he has never fared well on the course for the DP World Tour Championship in Dubai next week.
