After another top 20 finish at the PGA Championship, Adam Scott says he must collect some silverware if he can call this season a success. The Australian world number six has had a stellar year and is perhaps the best credentialed golfer yet to win a title this season despite a string of good finishes. He was in the hunt in the year&aposs fourth major, one shot behind eventually winner Rory McIlroy after round two, but poor chipping and putting cost him dearly at the end of round three before McIlroy streaked the field for his second major with an eight-stroke margin. “I just never really got it going,” Scott said. “Rory had it in his hands today, and put it out of everyone&aposs reach.” Scott settled for a tie of 11th with compatriot Geoff Ogilvy with no one able to match McIlroy at 13 under. The 32-year-old had harboured hopes of redemption starting a rain-delayed third round one shot off the lead. Just weeks after his British Open meltdown, where he surrendered a four-stroke lead in the final round, Scott looked on track at Kiawah Island after the conditions settled down but fell by the wayside like the rest of the top 10. Still, the finish was Scott&aposs seventh of his past eight in the top 25 at majors. His form line this season in majors has been very good; tying for eighth at The Masters, tying 15th at the US Open, second at the British Open and now 11th at the PGA Championship. Yet Scott still feels he has plenty of work to do. “No not yet – I have to win something,” he said. “I feel like I have played too good this year to not have a trophy somewhere so I&aposll be determined in New York, Boston, Indy or Atlanta to get my name on one somewhere. “But I think I have to take a lot of stock out of what I did this year in the majors and just try to improve a little bit. “I just have to keep at it, keep practising and, to try to play against guys like Rory, I am going to have to play great. “The game is right there and I have eight months to think about it and get ready for the next major.” Ogilvy came close to a second consecutive top 10 finish at a major with a pair of 70s to finish. “I am playing well enough to be right up on top of leader boards with a few holes to play but I need to make a few more putts and have some things go my way. It&aposs getting there,” Ogilvy said.
