Kenny Perry shot a 10-under 62 Saturday to set the Champions Tour's 36-hole scoring record in the Ace Group Classic.
Perry made five birdies on the front, and six more on the back with a bogey on No. 15. He bounced back from that with birdies on the last three. Mize and Lehman were tied for second most of the day, then Mize birdied No. 18 to move into sole possession of second.
Langer set the tournament scoring record last year at 20 under.
