Four days after beating Bernhard Langer on the fifth extra hole in a Monday finish at Royal Birkdale, Wiebe had eight birdies in a bogey-free first round at TPC Twin Cities.
Running on adrenaline after the long week in England was compounded by travel issues that prevented him from getting to Minnesota until Wednesday, Wiebe made a 35-foot birdie putt on the fifth hole and a birdie from the off the fringe on No. 7. After those putts, playing partners Nick Price and Jay Haas told Wiebe to "Keep riding that pony."
Wiebe, slowed by right elbow and back ailments earlier this year, birdied five of the last seven holes on the front nine and added birdies on Nos. 12, 14 and 16.
Perry is making his first since winning the Senior Players Championship and U.S. Senior Open in consecutive starts for his first major victories. He skipped the Senior British Open because of a family commitment.

Pavin had a bogey-free round that featured four birdies on the front nine and three on the back.
