Three-time major winner Jordan Spieth regained second spot in the world golf rankings on Monday despite losing to top-ranked Dustin Johnson in a play-off at the Northern Trust Open on Sunday.

Johnson strengthened his grip on the world number one ranking thanks to his first win since injuring himself falling down stairs before April's Masters.

Rising Spanish star Jon Rahm, who only turned professional last year, continued his sensational rise by breaking into the top five for the first time after finishing tied for third with Venezuela's Jhonattan Vegas in New York.
