Paul Casey's future now looking a whole lot rosier On 10-under, is Casey's countryman, Rober Rock, after a 71. It will take something special for Casey to overhaul the leaders, but the look is back in the eye of the player, who just four years ago became the first Briton to reach the world's top three since Colin Montgomerie in the late Nineties. As ever in a golfing slump, it has been the short stick which has largely been to blame. Casey arrived in Co Kildare calling it "the last piece in puzzle," assuring anyone who would listen that the ball-striking was back to its peerless best. He has switched to a new Nike putter and the transformation has been as obvious as it has been exciting for Casey. "I knew that as soon I had a good putting day I would shoot a low round," he said. I'm ecstatic to have moved up that leaderboard as it validates what I've been saying - the ball-striking is there again. It's funny, but every time I made a mistake out there, I seemed to clean it up with a wonderful putt. I took advantage of the par-fives and the driveable par four. Casey has not won since 2011, after which he broke his collarbone in a snowboarding accident. Having finished third on this Carton House layout in 2006, he can sense that a return to the winner's enclosure is nigh. "I know I can play well around here and feel I have a chance to win," Casey said. It might take something very low but of I keep playing the way I am then it's possible. Luiten is an ominous adversary. The 27-year-old is on a tremendous run of form, having won in Austria two events and then finished in the top 10 in Munich last week. He is not fazed by someone of Casey's stature looming. "I don't care who is behind me, so long as they stay behind me," Luiten said. On the same mark as Casey is the young Scot Scott Henry, who followed up his 64 with a 69 and, who has the capability of being involved in what could be a shootout worthy of this fine old tournament.
