"I don't like the nine-and-a-half, ten years in between the two titles, but it's a quality win," said Austin, who earned $756,000 for the victory. "I've had three chances and all three having been playoffs."
Herron birdied the 18th in regulation to force a playoff with Austin, who bogeyed the 72nd hole. Both players closed with rounds of four-under 66 to end the tournament tied at 10-under-par 260.
In the playoff, Austin, 40, ripped a long drive down the middle of the fairway. Herron knocked his second onto the green some 45 feet from the hole. Austin stuck his second inside five feet.
Herron's birdie try came up short. Austin sank his birdie try.
