Wiebe rallied during the final nine holes last week to tie Bernhard Langer at Royal Birkdale and then won what turned out to be a five-hole playoff that stretched over two days.
That victory was Wiebe's fourth on the Champions Tour after he had won twice on the regular PGA circuit.
He turned in a bogey-free round at the TPC-Twin Cities course Friday and owned a one-shot advantage over Kenny Perry and Corey Pavin. Peter Senior, Tom Pernice, John Riegger, Bart Bryant and Jeff Brehaut were all at 66 in a tie for fourth while Colin Montgomerie and Hall Sutton both turned in a 67.
