The Field vs. Jason Day

Jason Day saved his best for last at TPC Southwind, carding a 4-under 66 in the final round thanks to three birdies on the front, and three more on the back. It's his fourth straight time shooting 70 or better on Sunday, but he'll need to maintain focus through the mid-rounds to stay in contention. Day ranks second overall in scrambling, one of the key metrics at Olympia, with its thick rough, and contoured greens. Day won the BMW Championship in 2015 in Lake Forest, Illinois, shooting an opening round 61 (10-under), so we'll see if he can regain that magic. Risk a half-unit on Day to win outright.
