(Reuters) - World number two Dustin Johnson conjured up memories of John Daly as he plundered a course record nine-under-par 63 to earn a share of the second-round lead at the rain-hit BMW Championship in Indiana on Friday. The U.S. Open champion joined fellow American Roberto Castro (65) at 14-under 130, three strokes clear of Englishman Paul Casey (66). World number one Jason Day (67), FedEx Cup points leader Patrick Reed (70) and Monday's Deutsche Bank Championship winner Rory McIlroy (72) all trail by 10 strokes.
