SYDNEY, Nov 27 (Reuters) - Sydneysider Matt Jones stormed into a three-stroke lead with a three-under-par 68 in the second round of the Australian Open on Friday as reigning champion Jordan Spieth moved into a share of third despite another frustrating day.
The American world number one also carded a 68 to stand four shots off the pace set by Jones on seven-under and a stroke behind big-hitting local Todd Sinnott, who was second after a 70.
Although conditions were markedly calmer than on Thursday, when temperatures soared and gusts of wind swirled across the fairways at the Australian Golf Club, good scores were still at a premium.
