He has now made 17 birdies in two rounds, his best ever result on the PGA TOUR, though that wasn't the most important number. Tiger said that is all it takes to get him really going, just one good shot; "It left me a two-shot lead, all I need is one shot, and as soon as I feel it on one, I can pretty much carry through. And I did that today." Two shots behind Tiger,who has a tournament total of -13 under par, is Graeme McDowell. who had a second round of -5 under par 67. which gave him his total of -11 under par for the tournament. Graeme expects the greens, which are already firm and crusty under a week of sunshine and dry air, to get worse. He was pretty cynical with his remarks; "I guess they can let this place go since they're going to tear it up on Monday." Donald Trump, who owns the entire resort plans a big makeover on TPC Blue Monster, with construction to start right after the tournament. If that's the case, it could be reminiscent of the Arnold Palmer Invitational a year ago, where Tiger outlasted G-Mac on the final day. Graeme continued with his assessment of this tournament; "Tomorrow is not about winning the golf tournament, tomorrow is about maintaining position, maintaining the way I'm playing and trying to give myself a chance come Sunday afternoon. It doesn't really matter who I'm playing with tomorrow, Tiger always brings his own interesting little circus inside the ropes. But like I say, I've been there many times and I always look forward to playing with him. I saw Phil sneaking up the leaderboard there behind me and I said; Let's spoil this party tomorrow. I'm sure they would have liked Tiger and Phil in the last group tomorrow, but I certainly will enjoy the position of being in the last group. That's where I want to be." Tied in third position at -10 under par are Phil Mickleson and Steve Stricker, Steve gave Tiger a tip about putting, he may be thinking right now that was probably not a wise thing to do, and he said as much; " Yes and no, not really. It's good to see him putting well and playing well. It's good for us, it's good for the game." World Number One Rory McIlroy had six birdies today, along with three bogies, at least he is in red numbers and is buoyed up by the thoughts of improvement; "It's nice to shoot something in the 60s, definitely something to build on over the next couple of days.I saw a lot of positives, I saw a lot of good signs out there. It's about the ball‑striking and the ball‑striking is getting there. Days like today were very pleasing because it shows that I'm going in the right direction." Rory is currently at -2 under par for the tournament, tied in 32nd place.
