David Hearn birdied the 16th to go to 19-under to tie the lead.
Then on the 18th, the young Dallas-native Jordan Spieth chipped it out of the bunker with a great shot that hit the flag pole and sunk in for birdie to force a 3-way tie for the lead.
Zach Johnson had to hit his 2nd shot on the 18th from behind a tree and the ball goes into the drink...Johnson would be out of contention after the bogey.
Then after David Hearn bogeyed the 18th, Jordan Spieth tapped in his par putt on 18th and became the 4th youngest champion on the PGA Tour since 1900, at the age 19.
