SILVIS, Ill. — 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 6-under 65 Thursday for a share of the lead with Patrick Rodgers and Ryan Moore in the suspended first round.
"I don't know what it is, but I love the golf course," Johnson said. "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."
Play was delayed for 3½ hours at TPC Deere Run by a storm that dropped just more than an inch of rain. The round resumed at 3:08 p.m., with none of the afternoon starters in position to finish the round before dark.
"As far as the start and stop, we're used to that," Johnson said. "That's not any secret. It happens all the time. There's days where there's a 30-minute delay, there's days where, shoot, it takes 30-some odd hours to play 18 holes. I'm used to it."
Johnson had five birdies in a seven-hole stretch in the bogey-free round.
Jordan Spieth chose not to defend his title because he didn't think it would be appropriate in light of his decision to skip the Rio Olympics.
Scott Pinckney and Scott Brown were a stroke back at 66 in the penultimate tournament for players to qualify for the FedEx Cup playoffs.
Singh leads major
UPPER ARLINGTON, Ohio — Vijay Singh rebounded from a bad shot on the 17th to birdie the final hole 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 53, the Fijian shot 4-under 66 at Scioto Country Club in suburban Columbus.
"I'm driving the ball well," said, Singh, who hit 13 of 14 fairways and 16 of 18 greens. "I'm hitting my irons good. Playing the regular tour, I've been playing pretty decent out there, too."
Miguel Angel Jimenez, Jeff Gallagher, Michael Allen, Gene Sauers and Glen Day shot 68. John Daly and defending champion Jeff Maggert each shot 70.
