Clarke made three birdies in the first six holes followed by a bogey on the 8th. He finished the round with 10 consecutive pars to fall eight shots off the lead.
Tim Petrovic shot a 4-under-par 66 to reach 12-under-par to maintain the outright lead in his bid for his first career PGA TOUR Champions title in his 144th start.
Petrovic offset three bogeys with seven birdies; after finding just three of 13 fairways off the tee in round one, he improved to eight of 13 in Saturday’s second round.
Making his 100th PGA TOUR Champions start this week, Ken Duke has positioned himself for his first win and third consecutive top-10 finish in the Shaw Charity Classic. Duke shot a 6-under-par 64 to leave himself on 10-under-par, 2 shots behind Petrovic.
Three days after his 60th birthday, Scott Dunlap made eight birdies and no bogeys to post his PGA TOUR Champions’ career-low score of 62 and position himself for a second career win on PGA TOUR Champions.
Dunlap is 8-under-par and in a tie for third place alongside Billy Andrade, Robert Karlsson and Dicky Pride.
Fred Couples and Colin Montgomerie are both 5-under-par with home favourite and former Masters champion David Weir on 2-under-par.
