DES MOINES, Iowa (AP) — Mark Calcavecchia made a 15-foot birdie putt on the final hole Saturday for a 4-under 68 and a one-stroke lead heading into the final round of the Champions Tour’s Principal Charity Classic. Calcavecchia had a 9-under 135 total at Wakonda Club. The 54-year-old Calcavecchia has two victories on the 50-and-over tour after winning 13 times on the PGA Tour, including the 1989 British Open.

Joe Durant was second after a 68. Paul Goydos, Brian Henninger and Michael Allen were tied for third at 7 under, all shooting 70. Calcavecchia has struggled most of the year following offseason surgery on his right hand. But he birdied the last two holes Saturday to grab the lead from Durant.
