Ryan Moore shot two more rounds of 6-under 65 on Saturday to take the third-round lead in the John Deere Classic, finishing at 9:25 p.m. in nearly dark conditions.
After opening Thursday with a 65, Moore never got on the course Friday in the tournament that finally got back on schedule Saturday when the players raced to finish before dark.
Play was delayed 3 1/2 hours Thursday when an inch of rain fell, then the start was delayed five hours Friday after an overnight storm dumped another 2.4 inches on the soaked course.
Morgan Hoffman and Ben Martin each shot 62 to more within a stroke at 17 under.
The 33-year-old Moore has four PGA Tour victories, winning the CIMB Classic in 2013 and 2014. He was third in March in the Valspar Championship and has five top-10 finishes this season.
In the third round, Moore birdied the par-4 14th, hitting a 60-yard approach to a foot, and made a 6-foot birdie putt on par-3 16th. He parred the final two holes, putting out on the par-4 18th with a large scoreboard providing just enough light to see.
