At this time last year, Anthony Kim looked like he was shaping up to have an excellent year. And then he had to take a few months off to get thumb surgery. Since returning, he hasn’t managed to put up consistent performances. Perhaps Friday’s round at the Shell Houston Open is a sign of more positive things to come. (We’ll see.) The defending champion of this event, Kim, got hot, rolling in eight birdies on his way to a bogey-free 64 to surge into contention.
