SILVIS, Illinois — Michael Kim took a four-shot lead Friday at the John Deere Classic in the Quad Cities, which was suspended twice because of weather concerns.

Kim, who is winless in 84 career PGA Tour starts, was 16 under through 35 holes, with the second round to be completed Saturday morning.

Kim birdied eight of his first 14 holes without a bogey to race past first-round leader Steve Wheatcroft, who shot 68. Wheatcroft was 12 under along with David Hearn (64) and Johnson Wagner (66).

Francesco Molinari was 11 under along with Matt Jones and Bronson Burgoon, who made two eagles on Friday and was 8 under for the round with three holes to play.

The 24-year-old Kim, a former standout at Cal, Kim, pushed his lead to three shots by hitting a wedge from 111 yards to within 5 feet for birdie on the par-4 13th.

Kim, who had missed the cut in 14 of 22 starts this season, followed that up with a 13-footer for birdie on the par-4 14th.

Hearn has had an up-and-down year, missing eight cuts. But his irons have been dialed in at TPC Deere Run. He birdied three of the four par-3s on Friday.

“I think I just have good feelings around this golf course. I’ve always enjoyed playing it. I am putting the ball in play off the tee, which isn’t as hard here as some of the other golf courses we play. But when I am doing that, I’m giving myself good chances for birdie,” Hearn said. “The putter has been hot.”

Wheatcroft, who led on Thursday after the best round of his career, made three bogeys on his back nine. But he’s still in position for his first top-10 finish of the season.

“Just need to tighten things up a little bit, and hopefully a good night of rest and get hydrated here and we’ll come back out (Saturday),” Wheatcroft said.

Molinari got his first official PGA Tour win two weeks ago at the Quicken Loans National outside Washington, and the Italian continued his strong play at TPC Deere Run with rounds of 6-under and 5-under.

Renowned for his ball-striking, Molinari hit 12 of 14 fairways and 14 of 18 greens in regulation both Thursday and Friday.
