Herron stretches lead in Bob Hope Classic

Tim Herron, who won the last of his three PGA Tour titles in 1999, opened a four-shot lead after four rounds of the Bob Hope Classic.

Herron began the day tied for the lead with Stephen Ames of Trinidad but had eight birdies in a 12-hole span en route to a seven-under-par 65 at Indian Wells Country Club, La Quinta.
