I wasn't able to watch much Tiger this weekend, but just looking at the stats he's still having some swing consistency issues and putting issues.
His drives are averaging over 300 yds so he still has power, but his GIR isn't that great. He's still well behind the leaders in putting stats, but part of that may also be due to issues with iron accuracy and missing scoring spots on the fairways.
On a web-broadcast I just watched Tiger's warm-up swing on the par-3 15th hole, and he looked like he was really thinking during his two practice-swings, but also appeared relaxed. Since he's not going to win he's taking the right attitude to use the last round to practice a few things. Hope he gets things fixed for next week.
