South African Tim Clark flirted with golf&aposs magical 59 mark before settling for a nine-under 62 to take the halfway lead at the Deutsche Bank Championship. He was 11-under on the day through 16 holes, needing only one more birdie to shoot 59, but he bogeyed the final two holes instead. Clark leads at 14-under 128, one stroke ahead of Canadian Mike Weir, while Nick O&aposHern is the best Australian, seven strokes off the pace, with Stuart Appleby and Jason Day another stroke back. Weir, who matched the course record with a 10-under 61 in the first round, made a slow start to the second round but recovered from two bogeys to roar back with five birdies in a three-under 68. American Ben Curtis and Fijian Vijay Singh share third place at 12-under with rounds of 65 and 66 respectively, with Singh&aposs bid to claim the prize as the FedEx Cup winner gaining pace. He&aposs being chased for the big bucks by Spaniard Sergio Garcia, who Singh pipped in a playoff last week at The Barclays. Garcia is one stroke back of Singh and Curtis along with Ernie Els, Kevin Streelman and Jim Furyk. Meanwhile, under-fire Englishman Ian Poulter and Paul Casey did not help their Ryder Cup causes as they missed the cut. Poulter and Casey, who are among several players vying for a captain&aposs pick on the European team, squandered their final chance to impress Nick Faldo before he names his selections on Sunday. Casey finished at one-under 141 after the second round, with Poulter three strokes further back.
