D.A. Weibring shot his second consecutive 5-under 67 on Friday to take a two-stroke lead after two rounds of the Jeld-Wen Tradition at Crosswater Club.
Weibring, who has one top-10 finish and is 49th on the Champions Tour earnings list, was two strokes ahead of Tom Lehman, his first-round co-leader. Lehman shot a 69 and was at 136.
The Tradition is the fourth of five majors on the Champions Tour.
The 57-year-old Weibring is looking to win his first Champions event since the 2008 Senior Players Championship, also a major. That is Weibring's only major title of his career, including on the PGA Tour.
Weibring made five birdie putts ranging from 12 and 18 feet.
Gil Morgan, Jay Don Blake, Bob Tway and Fred Funk were tied for third at 137. Morgan, who will be 64 in September, is the most surprising of that group after shooting a second-round 69. Morgan doesn't have a top-20 finish this year and hasn't won on tour since 2007.
Tway shot a 67 that included five birdies on the back nine.
Funk, who shot a second-round 69, continued his hot play at Crosswater. In 14 Tradition rounds at the central Oregon golf course, Funk is 42 under par.
Four strokes off the lead at 138 were Bernhard Langer and Jay Haas.
Langer, who shot a second-round 69, is attempting to become the second player in Champions Tour history to win three consecutive majors. Earlier this summer, Langer won the Senior British Open and U.S. Senior Open.
Haas had Friday's low round with a 65. He shot a 6-under 30 on the front nine, then added a birdie at No. 15.
Five strokes behind Weibring was a group of five including local favorite Bob Gilder of Corvallis.
Heading a group of five players at 140 was David Frost, who tied a Champions Tour record with a 25-under 191 total at the 3M Championship two weeks ago. Frost shot a 66 Friday, though the round was marred with a double bogey at 18.
Also shooting 66 on Friday was Hal Sutton, who was at 141.
Defending champion Mike Reid bounced back from an opening-round 79 with a 69.
