Roberto Diaz shoots a 9-under 62 to lead after round 1 of the John Deere Classic at TPC Deere Run in Silvis. Diaz heads into tomorrow's round 2 with a 2-shot advantage over Adam Long and Russell Hendley. Diaz goes off from the 10th tee at 8:50 a.m. Friday. A half-dozen players are sitting at 6-under.
