SAN DIEGO, Jan 31 (Reuters) - American Ben Crane, helped by three lengthy birdie putts, clinched his first PGA Tour title in more than four years with a one-shot victory at the San Diego Open on Sunday.

Crane overhauled third-round leader Ryuji Imada of Japan with three birdies in the first five holes and survived a nervy finish to card a two-under-par 70 for a 13-under total of 275.
