Golf: Jordan Spieth holds nerve to win Valspar C'ship on 3rd play-off hole

PALM HARBOUR, FLORIDA (Reuters) - American Jordan Spieth won the Valspar Championship in dramatic fashion on Sunday, triumphing in a three-way play-off, with a superb 28-foot birdie putt on the third play-off hole.

Spieth outlasted fellow Americans Patrick Reed and Sean O'Hair at the Innisbrook Resort in Palm Harbor, Florida, after all three had finished 10-under-par for the tournament.

The victory is the second of the 21-year-old Spieth's career on the PGA Tour, following his win at the John Deer Classic in July 2013 and will move him to sixth in the world rankings.

With no difference between the trio on the 18th and 16th holes, the contest went to the par-three 17th, where Reed, who found the bunker, and O'Hair left themselves with par-putts before Spieth drained his birdie putt.

"Putts like that are luck, right?" said Spieth. "If that doesn't hit the hole, it's four feet past. I guess it was just my day."
