The best round of Jordan Spieth’s life, as he called it Sunday in Australia, vaulted the 21-year-old well past the field at the Emirates Australian Open in Sydney, earning him his second win as a professional.
Spieth began the final round tied for the lead at five under with Australians Greg Chalmers and Brett Rumford, but took a two-shot lead through five holes Sunday before running away with the win. He made four birdies in his first seven holes, then closed with four more birdies over the last five holes for a final round of eight-under 63 and a six-stroke victory in windy conditions.
Spieth’s Sunday 63 set the course record at Australian Golf Club, a Jack Nicklaus-designed course. However, Spieth’s best ballstriking round (at least according to the stats) came Saturday when he hit 72.2% greens in regulation and shot two-under 69. On Sunday, Spieth hit 61.1% GIR. His ballstriking on the weekend was much better than Thursday and Friday, when he hit 55.6% and 44.4% GIR respectively.
Spieth used Titleist AP2 irons in his 3- through 9-iron with True Temper PX 6.0 shafts.
But the club that made the biggest difference, especially during the final round, was Spieth’s putter. The American had only 21 putts on Sunday and averaged only 1.36 putts per GIR. Spieth expressed tremendous confidence in his putting during an interview on the driving range prior to the final round.
The putter Spieth used is a Scotty Cameron 009 prototype. His success on the greens comes as little surprise, having finished the 2013-14 PGA Tour season 20th in strokes gained/putting.
