McDowell hot on Woods' heels

A former US Open champion from the North was Tiger Woods’ closest challenger at the WGC-Cadillac Championship in Miami – but it was Graeme McDowell and not Rory McIlroy trying to stay in touch with the 14-time major winner.

McDowell added a flawless 67 to his opening 66 for an 11-under-par halfway total in the event on the Blue Monster at Doral, finishing one shot ahead of Phil Mickelson after the left-hander returned a second straight 67.
