Tiger Woods may have four wins at Cog Hill but this is Mark Wilson’s home course, so maybe Wilson will have a bit of home field advantage when they tee off together today at The BMW Championship. The recent redesign of Cog Hill may have made the greens less familiar to Tiger but it did not stop him from using a mere 25 putts on his way to a 67. Wilson matched Tiger’s putt total but used one less shot to scratch out a 66 for the second round. Woods and Wilson have gone head to head before. In the 1992 US Junior Amateur Championship Woods defeated Wilson 1 up to win his second of three consecutive Junior Amateurs. It’s a small world isn’t it?
