BIRMINGHAM, Ala. (AP) Kenny Perry maintained a one-stroke lead over Bernhard Langer and Billy Andrade with a 2-under 70 in Friday's second round of the Regions Tradition.

Perry followed a bogey-free opening round in the first of the year's five PGA Tour Champions majors with three birdies and a bogey at Greystone Golf and Country Club. The 2014 Regions Tradition winner at nearby Shoal Creek is at 10-under 134.

Langer picked up one stroke with a round that also included one bogey. Andrade birdied the final hole for a 68, including six birdies and two bogeys.

Three players are at 8 under, including Gene Sauers, Scott McCarron and last year's runner-up, Kevin Sutherland.

Tournament officials went to a two-tee start because of weather concerns.
