It's been a trying season for Jason Day, who this week is making one last-ditch attempt to salvage a winless campaign. He posted a 3-under 67 in the second round of the Tour Championship on Friday -- which was helpful, except for the rough patch. Day bogeyed the 12th, 13th and 14th holes, keeping him from a score that could've vaulted him near the top of the leaderboard entering the weekend. "Got to stop making these silly errors," he said afterward. "It's really frustrating, because I get really good momentum through the first part of my round and the mid-to-the late part of my round, I rattle off a couple bogeys."
