AUGUSTA, Ga. -- Jordan Spieth is off to another great start in the Masters because of the way he finished.
His two biggest rivals were left behind because they couldn't.
Spieth capped the only bogey-free round in the wicked wind at Augusta National by making a 15-foot par putt on the 16th hole and hitting an 8-iron into 6 feet for birdie on the final hole for a 6-under 66 and a two-shot lead, the first step in his bid to win another green jacket.
Jason Day couldn't keep pace. On the verge of tying for the lead late in the round Thursday, Day dropped five shots in three holes and had to settle for a 72.
