So an amateur leads heading in to the final day, alongside Jason Day and Oosthuizen. Spieth one shot back and Harrington one further back. Adam Scott 3 shots off.
Should be a cracker. Spieth going for the treble, Day and Sergio Garcia for their first after so many near misses, Harrington a two-time champ, Scott trying to win his first since that 4 shot choke and an amateur trying to win.
