Graeme McDowell just needs to hold on to take home the World Challenge, presented by Northwestern Mutual. McDowell is 16-under with just one hole left, two shots clear of second-place Keegan Bradley, who is on 17.

McDowell made his run with consecutive birdies at 10 and 11. While it looked like he might come back to the field with a bogey at 13, he made birdie at 16 to stretch his lead. That birdie is proving crucial, as Bradley has turned it up on the back nine with three birdies, but it doesn't appear as if it will be enough.

The field is having little trouble at Sherwood Country Club, where rain has made the greens receptive. It has also slowed the fairways, though, so the course is playing very long. As a result, bogeys haven't been common, but neither have strings of birdies.

Bo Van Pelt is in the clubhouse in third place, at 10-under. Van Pelt is one shot ahead of Tiger Woods, Rickie Fowler and Jim Furyk, who are all at 9-under.
