CHARLESTON, W.Va. - The superintendent of the West Virginia coal mine where an explosion killed 29 men was charged Wednesday with conspiracy to defraud the federal government, becoming the highest-ranking employee to face criminal prosecution in an investigation that appeared to be moving steadily up the corporate ladder.

Former Upper Big Branch mine boss Gary May, 43, of Bloomingrose, W.Va., is named in a federal information, a document that signals a defendant is cooperating with prosecutors.

He is the second employee of Massey Energy, the company that owned the mine at the time of the 2010 tragedy, to face prosecution.

MARANA, Ariz. - One putt changed everything for Ryo Ishikawa and sent Riviera winner Bill Haas home early Wednesday from the Match Play Championship.

But the Japanese star holed his birdie putt, Haas missed, and Ishikawa won on the 18th hole with a par to advance to the second round at Dove Mountain.

Five of the opening six matches went to the 18th hole, and three required extra holes.
