Rahm wins first PGA title with late surge

A back nine that included two birdies and two eagles helped Jon Rahm claim his first PGA Tour victory at the Farmers Insurance Open.

The 22-year-old putted 60 feet for an eagle on the 18th to become the youngest-ever winner of the Torrey Pines tournament in San Diego.

Rahm's 13-under for the tournament saw him win by three strokes over Charles Howell of the US and Pan Cheng-tsung of Taiwan, with the Spaniard carding a 65 on the final day to overcome a three-stroke deficit on overnight leaders Brandt Snedeker and Patrick Rodgers, who both carded one-over 73s.

Rahm had a bogey at the first hole of the day, but birdies on three, five, 11 and 17, plus eagles on 13 and 18 gave him seven-under-par for the round.

"I can't explain what went through my mind and I saw the replay and my reaction and I don't even remember doing what I did. It's hard to explain," said Rahm, who is tipped at 100/1 to win the 2017 PGA Championship.

"Just to get in that position is so hard and I'm so blessed to say this is the third chance I've had to win in my PGA career. Thanks to 13 I got into it and thanks God I kept it going."

A five-under 67 by Keegan Bradley saw him leap 20 places up the leaderboard to finish fourth, tied with Justin Rose of England at nine-under par.
