Tony Finau shot a 4-under 67 to win the 3M Open by three strokes Sunday, erasing a five-stroke deficit with 11 holes left as Scott Piercy tumbled out of the lead down the stretch at windy TPC Twin Cities.
Piercy followed his tournament-record 54-hole score with a wince-inducing 76 to tie for fourth, four strokes back.
Finau finished at 17-under 267.
