Zach Johnson made himself right at home in the John Deere Classic — again.

From just up the road in Cedar Rapids, Iowa, the two-time major champion shot a 6-under 65 on Thursday, leaving him two strokes behind leader Andrew Loupe in the suspended first round.

“I don’t know what it is, but I love the golf course,” said Johnson, the 2012 winner at TPC Deere Run. “I love the putting surfaces. I do know the moment I feel like I can take this place down is the moment it can bite me, so I’ve still got to stay focused and keep the pedal down.”

Loupe topped the leaderboard at 8 under when play was suspended because of darkness. The tournament was delayed for 3 1/2 hours by a storm that dropped just over an inch of rain. The round resumed at 3:08 p.m., with none of the afternoon starters able to finish.

Loupe will resume play Friday with a 6-foot par putt on the par-4 15th hole. The 27-year-old former LSU player had five birdies in a seven-hole stretch on the front nine and added birdies on 11, 13 and 14.

Patrick Rodgers and Ryan Moore were in at 65 with Johnson, and Tom Gillis also was 6 under with two holes left.

Johnson had five birdies in a seven-hole stretch in the bogey-free round that he started on the 10th tee. The 12- time PGA Tour winner capped the run on the par-5 second and also birdied the par-4 sixth.

Senior Open

UPPER ARLINGTON, Ohio (AP) — Vijay Singh rebounded from a bad shot on the 17th to birdie the final hole Thursday and take a two-stroke lead after the first round of the U.S. Senior Open.

Still playing full-time on the PGA Tour at age 53, the big Fijian shot a 4-under 66 on a hot and humid afternoon at Scioto Country Club, the suburban Columbus course where Jack Nicklaus learned to play.
