Steve Stricker defeated Padraig Harrington on the first play-off hole at the Kitchen Aid Senior PGA Championship to earn his sixth PGA Tour Champions major.
Three-time major winner Harrington led the way for the first three rounds at Frisco, having got off to a flyer on Thursday by breaking the course record.
The Dubliner found himself behind Stricker by one shot as they headed to the par-five 18th hole at the Fields Ranch East course at PGA Frisco. With his back to the wall, Harrington reached the green in two and two-putted for birdie. That was enough to force a play-off once Stricker missed a long birdie putt.
But when they headed back to the 18th tee to start the play-off, Harrington drove into a hazard and Stricker was the one in position to make birdie. Harrington missed a birdie putt that would have extended the play-off.
Stricker, 56, has won each of the first two senior majors of the season, having captured the Regions Tradition earlier this month.
Afterwards, Harrington said: "Steve is probably the toughest guy you could ever play on a Sunday. He has to have the best wedge game in the world. Like he's a fabulous putter, he's a fabulous chipper, but his wedge play like at the first 14 holes was just spectacular."
Stewart Cink shot his fourth straight round in the 60s, a 69, to finish in third at 16 under. YE Yang of South Korea posted a 70 and was a distant fourth at 11 under.
Defending champion Steven Alker of New Zealand (71), Miguel Angel Jimenez of Spain (70) and Darren Clarke of Northern Ireland tied for fifth at nine under.
