Langer has won five times this season.
SNOQUALMIE, Wash. (AP) -- Bernhard Langer closed with a final-round 69 and pulled away from Nick Price down the stretch to win the Boeing Classic on Sunday.
Langer got his fifth Champions Tour victory this season, and the second in the greater Seattle area after this year after winning the U.S. Senior Open at Sammamish, Wash., a month ago.
His 18-under-par total matched Loren Roberts' tournament record from last year.
Langer made consecutive birdies at Nos. 15 and 16 to stretch his lead to four strokes with just two to play at the TPC at Snoqualmie Ridge to take a four-shot lead over Price.
Price (71) wasn't able to find enough birdies on Sunday to keep up with the Charles Schwab Cup leader.
Langer gave Price opportunities early as Langer missed the first three fairways of the day. Langer drove his tee shot into a bunker on the uphill 439-yard third hole, opening the door for Price to apply some pressure trailing by just a stroke. But Price's drive found the same bunker as Langer.
Langer was able to clear the lip easily and put his second shot just through the green while Price was forced to layup. Price couldn't save par and made bogey.
Price found the sand again off the tee on the fourth hole and his second shot caught the lip upon contact and landed in a greenside bunker. Price couldn't get up and down and made bogey, leaving a 6-footer short to save par.
After a big drive at the fifth, Price chunked a wedge and barely trickled on to the front edge of the green and three-putted from 50-feet for his third straight bogey.
But Langer allowed Price to hang around. A massive drive at the downhill 484-yard, par-4 11th left Langer just 86 yards out, but his second shot flew close to 20 feet past the hole and he three-putted for bogey. Price birdied the eighth and 11th to pull within two of the lead but couldn't get any closer to the methodical Langer.
Hometown favorite Fred Couples closed with a 67 to finish in third at 9 under. He struggled down the stretch on Saturday, shooting 4-over par on Nos. 15, 16 and 17 to fall out of contention. The Seattle native received a huge ovation after making birdie at No. 18 to close out his weekend.
