STERLING, Va. — Bernhard Langer knew it wouldn’t be easy to come from one stroke back to beat Vijay Singh, who’s five years younger, drives the ball 30 yards farther and routinely competes with players young enough to be his sons.

Ultimately, the 59-year-old German star’s confidence with the putter, a club that has frequently bedeviled him, was the difference as he edged past Singh in a tense back-nine duel to win the Senior PGA Championship at Trump National on Sunday.

Langer won his record ninth senior major and the only one that had eluded him during his dominant decade-long run on the 50-and-over circuit. He tied Jack Nicklaus’ record of eight majors last week with a comeback victory in the Regions Tradition. He’s also the first player to win the career “super slam” of all five senior majors.

Despite a few dozen protesters, the drama remained on the course at President Donald Trump’s club on the shores of the Potomac River, about 25 miles outside Washington. Trump, coming off a nine-day trip abroad, did not attend the final round.

Langer pulled ahead of Singh with 12-foot birdie on the par-4 16th. Singh three-putted 17 to give Langer a two-shot advantage. After Singh birdied 18, Langer calmly tapped in for par and a one-shot victory.
