This is it! The 2011 British Open is coming down to the wire with two Americans, Dustin Johnson and Phil Mickelson, trying to catch up to Darren Clarke for the lead. Northern Ireland's own is still alone at the top of the leaderboard at 7-under, but both Mickelson and Johnson are just three strokes behind Rory McIlroy, the heavy favorite, has struggled to stay in contention and dropped to 7-over par.
