MUNICH, Germany (AP) -- Martin Kaymer blew a six-stroke lead and then birdied the first hole of a playoff Sunday against Dane Anders Hansen to win the BMW International Open.
The 23-year-old German became the tournament's youngest winner despite his final round 75 to finish with a 15-under total of 273. Hansen birdied five of his last 11 holes to finish with a 67.
Kaymer had an 11th hole triple bogey but birdied the 18th to force a playoff. He won with a 200-yard approach shot that bounced to within six feet of the cup.
"I didn't want to lose here, this win was for my mother," said Kraymer, whose mother has a serious undisclosed illness according to German media reports. "After the 13th or 14th hole, I just kept fighting."
Kaymer earlier fell a stroke behind Hansen after two bogeys and the triple bogey -- caused by his failed gamble to drive past the water trap to reach the green.
The 2007 rookie of the year became the first German winner of the event in its 20-year history. Two-time Masters champion Bernhard Langer, Kaymer's countryman, tried without success 18 times.
It was Kaymer's second win after Abu Dhabi in January.
Sharing third at 13-under were English players Paul Casey, John Bickerton and Mark Foster.
