Zach Johnson is in the same spot he was a year ago at the John Deere Classic: Atop the leaderboard.
The defending champion opened with a 64 Thursday at TPC Deere Run, where he leads by one over Brendon de Jonge and Matt Bettencourt.
Three others are also at 6 under but still on the golf course.
Vaughn Taylor and Robert Streb are another stroke back, while three-time John Deere Classic winner Steve Stricker is at 4 under.
After seven birdies and no bogeys in the opening round, Johnson is now a combined 72 under dating back to the 2009 tournament.
Johnson is looking for his first win since last year's John Deere Classic.
