Si Woo Kim sealed his third PGA Tour victory with two birdies in the final three holes to hold the fast finishing Patrick Cantlay at bay.
Ancer's Saturday 73 knocked the Mexican out of win contention, but a Sunday 66 kept him in the payout money. He shared fifth with two others meaning he earns a full place payout for anyone on terms paying 7 or more places.
