Duke and Wi share lead at John Deere

Ken Duke and Charlie Wi each shot seven-under-par 64s to share a one-stroke lead after the first round of the John Deere Classic.

Duke, who along with Wi missed the cut at the AT&T National last week, started his round on the back nine and carded four birdies before picking up another four on the way home along with his solitary bogey at the par four eighth.
