Matt Kuchar / Heathcote / Getty Images Matt and all the other afternoon players had to endure more than two hours of delay in the second round of the tournament, due to dangerous weather conditions, that included lightning But that obviously did not upset Matt too much, as he climbed up to the top of the leaderboard. He currently has a one shot lead, being at -10 under par after 15 holes of his second round. The horn blew again just after Matt had hit his tee shop on the par 3, 16th, it was the second interruption of play on the day. " That's a bit of a bummer, it's no fun to wake up at 4:30 to get out here and play three holes. But we get used to it for what we do. I really got off to a great start, and then I kept playing some good golf. This course can give you trouble, but if you are hitting it good, you can make some birdies out here.I was hitting it good and able to fire at some pins today." Graham DeLaet, who has completed his second round is currently one shot adrift of the leader, at -9 under par for the tournament, and is also the clubhouse leader. Graham admitted the dreaded Horrible Horse-shoe got to him today, three bogeys at 3,4 and 5. "It definitely got me today." Defending champion Zach Johnson is -5 under par through 16 holes and has moved to -6 under for the tournament. The projected cut line is -1 under par.and if that cut line holds, the players who have already finished their rounds at even par or worse include: Charl Schwartzel, 15th in the world rankings; Corey Pavin, who was making his 30th Colonial start; David Hearn, who opened with a 64 on Thursday but shot a +8-over par 78 on Friday, which included a quadruple bogey at the par-3, 13th where he hit two balls into the water off the tee.
