According to the PGA Tour, no player since 1983 has won with a double-bogey and a triple-bogey in the final round, which is exactly what Fowler did. Not a record you want to own, but a win is a win.
Schauffele, who won the Tour Championship last year, hit 17 of 18 greens in regulation and leads the field in strokes gained/putting, a combination guaranteed to deliver a low score.
