Back on top of the world rankings, McIlroy is rated a 5/1 favourite to make it three wins in succession with a second US PGA Championship title at Valhalla this week.However, the Holywood man is not paying any attention to the hype surrounding his brilliant run of form, which saw him claim the Open Championship at Royal Liverpool and follow that with a first World Golf Championship victory in the Bridgestone Invitational.Since his emphatic return to form, the 25-year-old has been touted as becoming one of the world's greatest ever golfers.The legendary Jack Nicklaus said Rory had the ability and the talent to win 20 majors, smashing his tally of 18 titles.And Ryder Cup captain Paul McGinley predicted McIlroy could be on his way to dominating the game as Tiger Woods did in his prime stating golf was at the start of "Rory's era"."I don't really know how to answer that," McIlroy told his pre-tournament press conference at Valhalla. "Of course I've heard it and I've read it."Sometimes I feel that people are too quick to jump to conclusions and jump on the bandwagon and jump on certain things."I've had a great run of golf and I've played well over the past few months. I said at the start of the year that golf was looking for someone to put their hand up and become one of the dominant players in the game."I felt like I had the ability to do that and it's just nice to be able to win a few tournaments and get back to where I feel like I should be, which is near the top of the world rankings and competing in majors and winning golf tournaments."I'm not necessarily sure you can call that an era or the start of an era, but I'm just really happy with where my golf game is at the minute and I just want to try and continue that for as long as possible."People can say what they want to say, that's fine. But I can't read too much into it."I just need to continue to practice hard and play well and try not to read too much of the stuff that's being written, because if you read everything that was being written, I'd turn up at the first tee on Thursday thinking I'd already won the tournament."McIlroy added: "I don't think it's productive at all to read anything about yourself. I try not to. Obviously it's hard to stay away from everything, but I try to limit it as much as I can for sure."Rory is set to complete the opening round of the tournament in Kentucky late on Thursday night.Portrush golfer Graeme McDowell was one of the early starters in the opening round and finished with a 73, two over-par.Englishman Lee Westwood set the early pace finishing on six under.
