Englishman Justin Rose fired in a first round -7 under par 65, and rose to the top of the leaderboard, at the Arnold Palmer Invitational, leading the field by two shots. Justin Rose / Cannon / Getty Images Justin was playing in the group with Tiger Woods at Bay Hill on Thursday, he put on a clinic with the putter and ran off four straight birdies late in his round at the Arnold Palmer Invitational, presented by MasterCard. Justin did not see this coming, saying; "If you had said I would shoot a 65 on the range this morning, I would have probably said, `How many holes have I played?' And that didn't change much, the first five, six holes out there were a grind." The difference today was Justin's putting; " I dedicated myself at making a few changes and getting better at that part of the game. I've had some good days, no doubt. And today was probably the first real hot day I've had with the blade in a long, long time. We all know it's about consistency and that's what I'm still working towards. It's just fun to know that I obviously can do it, and I enjoy a lot of confidence from that." John Huh is in second place, at -5 under par, he had a chance to catch Justin late in the afternoon, but required a birdie on the final hole to do so. Unfortunately John found a fairway bunker on No. 9 and took a bogey for a -5 under par round of 67. John Rollins and Brad Fritsch were at -4 under par with rounds of 68, to be tied in third place. Tiger Woods had two uncharacteristic bogeys from greenside bunkers and definitely did not hit the ball as well as he did when he won The Honda Classic two weeks ago. It was his putting that kept his round reasonable, tied in fifth place after a round of -3 under par, 69. "It was one of my good ones, days happen like this. It was cool this morning, and it just didn't work out. But I scored well, and I kept myself in the tournament. I'm right there. Justin played a beautiful round of golf today. He had every single facet of his game working, so we had a good time out there. I got a lot out of this round, and I threw away a few shots as well."
