TUCSON, Ariz. - Marco Dawson made a 15-foot par putt on the par-4 18th for a 5-under 67 and the second-round lead Saturday in the Champions Tour's Tucson Conquistadores Classic.
Dawson, making his 21st start on the 50-and-over tour, opened with two birdies, made four in row on Nos. 7-10 and had his lone bogey on the par-3 17th. He holed consecutive birdie putts of 50 feet on No. 7, 18 on No. 8 and 35 on No. 9.
''I putted really well,'' Dawson said. ''I made some long putts. I also had a lot of saves.''
Dawson had a 10-under 134 total in the first-year event on Tucson National's Catalina Course, the longtime home of the PGA Tour's defunct Tucson Open.
The 51-year-old Dawson was second last year in the AT&T Championship in San Antonio. He's winless in 412 PGA Tour starts and has one victory in 161 events on the Web.com Tour.
''I was in this position last year and I thought I did pretty well on Sunday, but Michael Allen played really well down the stretch,'' Dawson said. ''I have no control over what everyone else does. If I play well, I'll be happy with that. The main thing is to play well.''
Wes Short Jr. and Bart Bryant were 9 under. Short eagled the par-5 second hole in a 66. Bryant, coming off a playoff loss to Lee Janzen last month in Naples, Florida, had an eagle on the par-5 10th in his 67.
Jerry Smith, the first-round leader after making a hole-in-one in a 65, dropped three strokes on the final two holes to fall to 8 under. He matched Dawson with a bogey on 17 and made a double bogey after driving into the left-side water on 18.
Michael Allen (67) and David Frost (71) were 6 under. Colin Montgomerie bogeyed the 18th for a 72 to fall into a tie for seventh at 5 under.
Bernhard Langer was tied for 10th at 4 under after a 71. He had five victories last year.
Kirk Triplett, the winner of the PGA Tour's final Tucson Open in 2006 at Tucson National, was tied for 20th at 3 under after a 73.
Jesper Parnevik was 1 over after a 74 in his Champions Tour debut. The five-time PGA Tour winner turned 50 on March 7. He missed the cut two weeks ago in the PGA Tour's Puerto Rico Open after injuring his back in a fall during a practice round.
Fred Couples was 3 over after a 75. Tom Watson was another shot back after a 72.
