Gene Sauers shot a 5-under 67 to move into a first-place tie with Miguel Angel Jimenez on Friday in the second round of the Regions Tradition, the first of five PGA Tour Champions majors.
Jimenez and Sauers were at 11-under 133. This was the first time either held or shared the lead after two rounds in a major.
Two-time defending champion Bernhard Langer was nine shots behind. He is trying to become the first to win three straight at the Tradition since it began in 1989.
Sauers completed his second straight bogey-free round. Jimenez had four birdies and a bogey for a 69 at Greystone Golf & Country Club, a day after matching the course record with a 64.
