Silvis, Ill. Robert Gamez, winless since taking two events in 1990 in his first two months on the PGA Tour, shot a 5-under 66 Saturday for a share of the third-round lead in the John Deere Classic.
J.P. Hayes, the second-round co-leader after a course-record 61, had a 67 to match Gamez at 18-under 195 on the TPC at Deere Run.
The start of the round was delayed nearly five hours because of a morning thunderstorm. Because of the wet conditions, players were allowed to lift, clean and place their balls in the fairways.
Mike Heinen, who opened with a 63 to top the field after the first round, was three strokes back at 15 under after a 66.
Chris Riley (66) and 2001 runner-up Briny Baird (68) followed at 14 under, and Tim Petrovic (68) was another stroke back.
Defending champion David Gossett shot a 67 to top an eight-player group at 12 under.
Fred Funk, tied with Hayes after the second round, also was 12 under after a 73. After opening with two bogey-free 64s, Funk bogeyed three of the first five holes in the third round.
