TUCSON, Ariz. (AP) Fred Couples shot an 8-under 65 on Friday in the Tucson Conquistadores Classic, leaving playing partner Steve Stricker two strokes back is his PGA Tour Champions debut.
Coming off a victory last month in the Chubb Classic, the 57-year-old Couples birdied five of the first seven holes in hot conditions, and added four more on the back nine before bogeying the par-4 18th.
Stricker birdied his first three holes in his bogey-free round on Omni Tucson National's Catalina Course. The 12-time PGA Tour winner turned 50 on Feb. 23. He will captain the U.S. Presidents Cup team in September.
Tom Lehman and Jeff Maggert shot 66, and Stephen Ames, Billy Mayfair and John Cook matched Stricker at 67.
Stricker missed the cut in last week in the PGA Tour's Valspar Championship and will make his next start in the big tour's Shell Houston Open.
Bernhard Langer had a 71 for his 30th straight round under par. Gil Morgan set the PGA Tour Champions record of 31 in 2000. Colin Montgomerie also is at 30, but he is not playing this week.
Bob Estes also made his debut on the 50-and-over tour, shooting a 70. The 51-year-old Estes won four times on the PGA Tour and has made six starts on the top circuit this season.
Defending champion Woody Austin also shot 70.
