The 55-year-old Lehman closed with 2-under-par 70 at North Shore and had a 15-under 201 total for his eighth senior title and first since 2012. He rebounded from bogeys on Nos. 13 and 14 – his only dropped strokes of the week – with birdies on Nos. 15 and 16, parred the par-3 17th and won on the par-4 18th.
“It wasn’t my very best performance today, but it was good enough,” Lehman said.
Michael Allen and Kirk Triplett tied for second, a stroke back. Allen shot 67, and Triplett had 68.
Lehman, the 1996 British Open winner, opened with rounds of 65 and 66 to take a three-stroke lead into the final round. He ended a 27-event victory drought and won $270,000.
“The check is sweet, but the trophy is sweeter,” Lehman said.
His last win was the Schwab Cup Championship at the end of the 2012 season.
Lehman, who was bogey-free and made 13 birdies in the first two rounds, parred the first 11 holes before birdieing No. 12.
“I had a rough start and wasn’t putting like I did the first two days,” Lehman said. “It put me in a bit of a bind. After 14, I told my caddie, ‘Let’s have the best four holes of the week.’”
