Dougherty, rated one of the most promising golfers on the European Tour, has missed 21 cuts in a row to slip to 791st in the world rankings, but refound his form Thursday with an eight-under 63 in the Swiss Alps.
U.S. Open champion McIlroy and 2010 PGA Champion Kaymer were two shots back after 65s in the morning rounds, sharing second with England's Gary Boyd and Korean Lee Sung.
In a star-studded line-up, world number two and his stablemate and British Open champion Darren Clarke were tied for eighth after 67s. In an unusual twist, the 29-year-old Dougherty was interviewed by his golf presenter wife Diane after his round and admitted he had not been easy to live with during his unexpected slump.
