MARANA, Ariz. -- Peter Hanson came into his match with Webb Simpson having won four of his last five matches at the Accenture Match Play Championship and reaching the quarterfinals last year.
The American hung tough on the back nine Friday, though, and eeked out a win when he made a 17-footer for birdie on the 18th hole. That 1-up advantage marked the only time Simpson had led in the match.
Hanson won two of the first three holes to take a 1-up advantage. Simpson then squared the match with a par at the seventh but Hanson responded by winning the eighth and 10th to carve out a 2-up advantage.
The Swede had take a drop in the desert on the par-5 11th hole and ended up conceding to Simpson there. When the reigning U.S. Open made a 14-footer for birdie at the 12th the match was square again.
Simpson had his troubles on the next par 5 and made bogey to give Hanson back the 1-up lead. But the former Wake Forest All-American squared the match with a par at the 14th hole and halved the next four with three pars and a birdie to set the stage for his heroics at No. 18.
"We went back and forth, it was almost like a boxing match, exchanging punches," said Simpson, who noted he has been sick all week. "But I had a feeling coming down the last couple holes, and we were able to hit some good shots coming in."
