Past champ Dustin Johnson fired a bogey-free course-record 9-under-par 32-31=63 in the second round of the BMW Championship to post 14-under 130, good for a share of the 36-hole lead with Roberto Castro.
The 2010 winner (Cog Hill G&CC) breaks the course record, previously 64 by seven players, six in the only other BMW at Crooked Stick GC, (2012), and Ryan Palmer earlier today in R2. Using a new putter this week, (TaylorMade Itsby Bitsy Ghost Spider), the South Carolinian circled Nos. 1, 3, 11, 13 and 14, highlighted by a 31'7" roll for birdie on the par-4 14th, adding eagle-3s at 9 and 15, both from off the green. His first was a hole-out from a greenside bunker at 9, 45'7" from the target, and the second was a 25-footer from the fringe at 15 that completed his scoring. Johnson split nine (of 14) fairways and pelted 15 greens in regulation, posting 1.467 putts per GIR and 1.719 SG: Putting, currently leading in both of those putting stats thru 36 holes. His 63 matches a season low (76 rounds), which he shot in the final round of the FESJC to back-door solo fifth.
