NORTON, Massachusetts: Tim Clark missed a chance to match the PGA record low score of 59 but a 9-under par 62 gave the South African a one-stroke lead after 36 holes at the PGA Deutsche Bank Championship.

Clark had a chance to approach the magical 59 mark after eagles on the second and fourth holes on his back nine of the round, but he finished with bogeys on the eighth and ninth, trimming his lead over Canada's Mike Weir.

"For a while, there was certainly a chance of 59," Clark said. "Although I had 59 on my mind once I made that (second eagle), it didn't affect my golf. I hit a couple of bad tee shots coming in, but I certainly hit a few good shots."
