I think if Tiger can keep to his gameplan with the irons on teeshots, he'll be -11 or -12 through tomorrow, assuming no major mistakes like 3-putting. I think McDowell will play solid again tomorrow, but I don't know if he'll manage to shoot another really good round. -10 through 2 rounds for him is my prediction. As mentioned, all the big guns at -4 will probably shoot good scores tomorrow (-4 or better), although they ARE playing in the tougher afternoon conditions, so who knows what will happen. I think Phil might go low tomorrow with a 65 or better to get up around -10. Overall, I think Tiger's got a really good chance to be leading through 2 rounds, but he will have a lot of big names hot on his heels going into the weekend even if he does manage to jump into the lead. This weekend, hopefully, will be a nice shootout.
