Stewart shot a -4 under par round of 68, while Bill Hass went one shot better at -5 under par 68 to tie at the top. Stewart is fired up for the duel tomorrow, stating that he can't wait; " Tomorrow is a great learning opportunity for me to get out there and be nervous and perform and try to stay in the moment and let it happen, I can't wait." Bill, was a co-leader after 36 holes at Bay Hill last week, today he made seven birdies over his last 13 holes to catch Stewart. Bill is under no illusions about how tough it is going to be tomorrow, there are 20 players separated by just four shots on a course where birdies are available, but the slightest miss could prove to be the unraveling of a good score; " Tomorrow you're going to have to play very well, you can't just hang on and hope everybody else will fall back." Steve Wheatcroft was tied for the lead when he shanked a shot from the greenside bunker on the 18th, the ball coming out at a 45 degree angle, missing the green completely. Steve said of that bunker shot; "If you don't catch it perfectly, it runs across the green into the water, I opened the club face just trying to hit a high soft one and obviously I missed most of the club face." Steve is one of four players just one shot back, they are; Ben Crane, D.A. Points and Jason Kokrak, all of them at -10 under par. The list of players at -9 under par is even longer, nine players to be exact, it is going to be exciting to watch this shoot-out tomorrow.
