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.

MacIntyre led the tournament from the end of the first round and started Sunday’s final round four shots clear of Scheffler, but the Scot found just one birdie all day on his way to a chastening three-over round of 73. With the door left ajar, Scheffler breezed inevitably through.
