Scottie Scheffler erased a four-shot deficit in five holes and then delivered a haymaker on the daunting par-3 17th by chipping in from 82 feet for birdie that carried him to victory Sunday in the BMW Championship for his fifth PGA Tour title of the year.

Royal Bank of Canada agreed to a multiyear deal to continue as title sponsor of the Heritage PGA Tour event at Hilton Head Island's Harbour Town Golf Links.

Robert MacIntyre leads at 16-under, but Scottie Scheffler lurks just four shots back as the BMW Championship final round tees off Sunday.

For the second week in a row, the No. 1- and No. 2-ranked players will be in the final group the first two days on the PGA Tour.
