But on the back nine, it was not the same and he could only manage one birdie against three bogeys.After finishing his round, Woods had a few words for the press. Here's what he said (via Playing Through):"It was better than yesterday, for sure. I've been more committed than I was yesterday. I made a few mistakes and overall the round was better, for sure. The start was better. The middle part of the round was better. I missed a couple of putts there towards the end I thought would have kept the round going and unfortunately it stalled out a little bit."Woods added:"I haven't played in six months. Things are not as sharp as they normally would be... There's some good in there, and just got to make sure that the good is more consistent than it has been."The other player returning to competitive activity during the Hero World Challenge, Will Zalatoris, also improved substantially from Thursday. Zalatoris posted a notorious -4 to improve his overall score to +5.The spectacular highlight of the day was set by Lucas Glover, who posted an ace on the 17th hole, a 168-yard, par-3 hole.
