Bo Van Pelt/getty images American Bo Van Pelt took control of the ISPS Handa International at Lake Karrinyup Country Club in Perth Western Australia, in the third round. Bo holed a 60 foot birdie putt on the 18th green, for a third round score of -5 under par and a tournament total of -12 under par, to take a one shot lead into the final round. Bo said of his monster putt on 18; " Once in a while a hole just gets in the way.I felt like I hit a pretty good second shot, just carried about five yards further. I was just trying to get the ball down there and two-putt and get out of there, and lo and behold, it goes in the hole. There's still a lot of golf to be played. It was just nice to finish with a birdie like that and hopefully take that into tomorrow. Jason is a great player, Grillo is playing well and he's probably going to come out and probably shoot a low one tomorrow. You've got to drive the ball straight and then put the ball in position on the greens, because they have a lot of slope and they are getting firm and they are getting fast." Jason Dufner, the World's Number Ten, and the highest-ranked player in the field was delighted to have given himself a chance going into Sunday. He also had a good third round, matching Bo's -5 under par round to sit alone in second spot, with a tournament total of -11 under par. " It was a nice day to get a good score and move up and have a realistic chance of not having to do anything crazy tomorrow and being in contention to try to win the tournament. Sometimes in the middle of a round, something happens that spurs you to some better play, and I got a little bit of a tough break on seven on my tee ball. Thought it would be in the fairway but hung up in the rough, which put me a good way back and I ended up getting into a bunker 70 yards or so and hit it over the back and then chipped in. So not really thinking that you're going to make birdie; in your mind you're almost feeling like maybe bogey might come on a pretty easy hole. Chipped in there and then hit one stone on nine and birdied 10, 11, 12." Emiliano Grillo started the third round with a four shot lead, but had a poor round of +1 over par, a very costly inward nine of 37 strokes did the damage as the Qualifying School graduate hopes to cement his place in the top 115 on The Race to Dubai. Emiliano currently lies in 112th place. With a tournament total of -10 under par, and third place, Emiliano is still only two shots adrift of the lead and will be sure to contest tomorrow. Tied in fourth place are Spain’s Alejandro Cañizares and England’s David Howell, and although the pair are five shots off the pace, they both have plenty to play for. In The Race to Dubai they are currently 70th and 71st on the list, meaning they both need a big finish to force their way into the top 60 players who will make the trip to Jumeirah Golf Estates next month.
