Jordan Spieth survives John Deere Classic cut; Jackson Koivun falls short in professional debut

At the John Deere Classic in Silvis, Illinois, Jordan Spieth narrowly made the cut at 3 under par after recovering with three back-nine birdies in his second round, while amateur Jackson Koivun missed the cut in his professional debut. Ben Griffin, the third member of their featured group, posted a strong second-round 65 to move up 40 spots on the leaderboard and will also play the weekend. Spieth, a two-time John Deere Classic winner, acknowledged a difficult day but managed to survive on the number.
