ORLANDO (Florida), March 17: Tiger Woods, who began the day four strokes clear, slumped to a two-over-par 74 to allow Len Mattiace to close within one shot of the lead after the third round of the $4 million Bay Hill Invitational Saturday.

Mattiace, who won the Nissan Open in February, turned up the heat on the world number one by firing a four-under-par 68 for a nine-under-par aggregate of 207.
