Justin Rose was joined at the top of the leaderboard by Bill Haas, at the Arnold Palmer Invitational, presented by MasterCard, at the conclusion of the second round at Bay Hill Club and Lodge. Justin Rose and Bill Haas / Greenwood / Getty Images Justin let the lead slip away from him on the last green, with a three putt, to finish his second round with a score of -2 under par 70, and a total of -9 under par. When asked about the three putt aberration, Justin replied; " But that was the only thing that hampered the day, really, all in all, an exciting day and I'm in a good position." He also gave credit to Tiger for the way he played today; " He's normally a fast finisher, and you can expect him to probably finish fast on the weekend. He did a lot of hard work today, he actually played really well. I thought he was probably a couple of shots away from shooting 64 today at times. I'm sure he was very disappointed because he actually played some great golf today." Justin also had to battle against a heckler in the crowd; "I was reading the putt thinking, `Might go a little bit right-to-left of the hole. Fairly straight overall.' And as I'm lining it up, someone is like, `It goes right. It goes right. It goes right.' So I'm like, `OK, thanks, buddy. It's just one of those annoying moments where you're having to then battle someone who planted a seed. And I hit a great putt that's in the middle with 4 feet to go and it goes left of the hole." Bill Haas said he had in his mind to get back the two shots he should not have dropped yesterday; "So to leave, basically giving two away, my goal today was try to get those two back and go from there. That was kind of my mindset today, and then I was able to keep it going." John Huh is in third place at -8 under par, he had a second round of -3 under par. Tiger Woods, partnering again with Justin today, hit the ball better but it did not improve his total for the round, in fact he was one shot worse off than yesterday. This was mainly due to three sloppy bogies to fall four shots behind going into the weekend, when he was actually just one shot out of the lead with three holes to play; " The good news is we've got 36 holes to go, we've got a long way to go. And certainly four shots can be made up." Tiger is tied in seventh place at -5 under par, after his second round of -2 under par.
