Russ Cochran (67) wins Principal by 1
Cochran finished at 11-under 205 at Wakonda Club. The left-hander, two strokes behind second-round leader Duffy Waldorf entering the day, broke a winless streak that stretched 35 tournaments.
Blake shot 69. He bogeyed the par-3 17th with his first three-putt of the tournament to fall a stroke behind. He had a chance to force a playoff, but his birdie try on the par-4 18th missed to the right.
