KAUPULEHU-KONA, Hawaii — It was a run that John Cook had never experienced in his long, successful career.

Cook birdied five straight holes after the turn to win the Champions Tour’s season-opening Mitsubishi Electric Championship on Sunday, shooting a second straight 8-under 64 for a two-stroke victory over Tom Lehman.

The 53-year-old Cook had eight birdies in his bogey-free round for a 22-under 194 total and his second straight victory. He finished last season with a successful title defense in the Charles Schwab Cup Championship.
