Four share lead at WGC-Cadillac Championship

Patrick Reed, Dustin Johnson, Matt Kuchar and Hunter Mahan share a four-way lead after the second round of action at the WGC-Cadillac Championship.

Rory McIlroy and Graeme McDowell are one shot behind the American leaders at the halfway stage at Doral.

Francesco Molinari of Italy and Wales's Jamie Donaldson are tied for second place with the two Northern Irishmen after another day that was affected by strong winds.

"It was just about playable," BBC Sport quotes McDowell as saying. "I can't remember playing in stronger winds, certainly on this side of the pond."

World number one and defending champion Tiger Woods is six shots off the pace after a 73, mixing five bogeys and four birdies in the process.
