Munich, Germany (My Sportsbook) - Martin Kaymer birdied the first playoff hole Sunday to defeat Anders Hansen and win the BMW International Open at Golfclub Munchen Eichenried.

Kaymer squandered a six-shot lead heading into the final round, thanks to two balls in the water en route to a triple-bogey eight at the 11th. He birdied the 72nd hole to force the playoff, then played brilliantly on the sudden- death hole.

The two headed back to the par-five 18th and Kaymer ripped a drive into the fairway. Hansen, who also birdied the 72nd hole, switched from a three-wood in regulation to a driver in the playoff and found a fairway bunker.

Hansen found a greenside bunker with his second, while Kaymer knocked his approach to seven feet. Hansen blasted out to 25 feet and, sensing he needed at least a birdie, gave the ball a firm rap eight feet past the cup.

Hansen, knowing Kaymer would not three-putt from seven feet, took very little time and missed his par putt. He marked and let Kaymer putt out for the championship.

Kaymer's eagle putt just missed, but he tapped in for the winning birdie.

"I was struggling today a little bit," acknowledged Kaymer, who became the first German winner of this event in its 20-year history. "I did things very well on the last two holes."

Kaymer shot a three-over 75, while Hansen posted a fine, five-under 67. The pair finished at 15-under 273.

John Bickerton (67), Paul Casey (70) and Mark Foster (68) tied for third place at 13-under 275.

Kaymer began the final round with a six-shot lead and two bogeys on the front nine brought him closer to the pack. It was two trips into the water at the par-five 11th that cost him sole possession of first.

His second shot found water in front of the green. Then Kaymer played his fourth from the drop area and that ball rolled into the pond. His sixth stopped 10 feet from the hole and Kaymer missed that on the left side. He tapped in for a triple-bogey eight.

"I hit it too thin," said Kaymer about his second shot. "I didn't really keep my patience there to be honest."

That dropped him into a tie for the lead with Hansen, who birdied three out of four holes around the turn, and Bickerton, who only played even-par golf the rest of the way.

Hansen moved into first by himself with a short birdie putt at the 15th. Kaymer wasted little time in joining him atop the leaderboard when he nearly holed his approach from the rough at 13.

Each player made a tough par save en route to the clubhouse. Hansen's came at the 17th when he converted a four-footer and Kaymer followed him later at the same hole with a six-foot save.

At 18, Hansen reached the green in two and had 25 feet for eagle. His try narrowly missed, but he tapped in for birdie to post 15-under par.

Kaymer needed at least a birdie at 18 to force a playoff and that's what he got. Like Hansen, Kaymer nearly holed his long eagle putt, but settled for a birdie that led to the playoff.

Kaymer claimed his second career victory and second win this year.

"I was in this situation in Abu Dhabi this year," said Kaymer, referring to his six-stroke cushion with one round to go. "It's really tough to play aggressive because you don't want to make any bogeys to give the other guys a chance.

"In general, I'm still happy."

Francois Delamontagne (71), Robert-Jan Derksen (65), Martin Erlandsson (66), Thomas Levet (72), Charl Schwartzel (73) and Henrik Stenson (68) shared sixth at 11-under 277.
