Winless on the 50-and-over tour, the 53-year-old Garwood began the run with birdies on Nos. 9 and 10 and played the back nine at Prestonwood in 5-under 31 in the final regular-season event of the year.
''The thing I remember is I had four lip-outs, so felt like it should have been lower,'' Garwood said. ''But it was fun. ... Obviously, when you shoot 7 under, everything's working. I drove it well, hit the irons pretty good and I started making putts. Putter was probably the best part, made a lot of putts even with the lip-outs.''
He birdied only one of the four par 5s - the ninth.
''I tried to hit 3-wood second shot and I hit it up in the rough, which is a mistake, but I gouged it out about 30 feet and rolled that one right in the heart,'' Garwood said.
The top 72 players on the money list after the tournament - and one player in the top 10 in the event but outside the top 72 for the season - will get spots in the Charles Schwab Cup Playoffs opener - the PowerShares QQQ Championship at Sherwood in Thousand Oaks, California, on Oct. 28-30. Brian Henninger, 72nd with 172,853, shot a 72. Garwood is 37th with $483,745.
Faxon had seven birdies and one bogey.
''I think the key to my round, I missed the fairway on one and then left it pretty far short of the green and I had a really tough little pitch shot that I zipped up the fringe and got it to like an inch,'' Faxon said. ''Then I made a long putt for birdie on two and a really long putt for birdie on three and it was just kind of the whole day was setting the tone by the first three holes.''
The 59-year-old Langer leads the tour with four victories and earnings of $2,512,659. He won the 2012 event and tied for third the last two years.
''It was a great day, especially the putter was hot,'' Langer said. ''Putted extremely well today. Made a lot of par saves and some really good birdie putts as well. Never hit one stiff, a gimme birdie, didn't have one of those, so all my birdies were putts.''
Jay Haas shot a 74, five days after winning in Newport Beach, California, at 62 years, 10 months, 7 days to become the second-oldest winner in tour history.
Defending champion Tom Lehman opened with a 72.
