Rory McIlroy's recent dip in form and clear frustrations on the golf course could be in response to his Masters win, and the realisation that he may never be fully satisfied in the game. The message comes from three-time major winner Lydia Ko. Dame Lydia, a member of the LPGA Hall of Fame and the reigning Olympic champion, is one of the women's game's most iconic players. The 28-year-old knows a thing or two about winning and the vicious cycle that comes with achieving your dreams. Since finally claiming the green jacket at Augusta in April, McIlroy has struggled. Underwhelming performances at the Truist Championship, the PGA Championship and RBC Canadian Open, where he missed the cut, were followed by a stern challenge at the Oakmont Country Club for the US Open, where he finished in a tie for 19th place. Ko has opened up about how being a professional means you're never quite satiated with your success. She also claimed that McIlroy may have to make "peace" with himself as he aims to get back on track and that he will be "greedy" just like other successful golf players. "I thought the way I think about myself would change when I got into the Hall of Fame and did a lot of things I really wanted to do before it actually happened, and I'm sure Rory is thinking the same where everybody was like 'Oh the Masters is the one he's missing, what if...' and he did it," Ko said to the press . "As much as I'm sure he's so happy and relieved, he's just as good as the day before he won it. I think that's what I kind of came to peace with. Sometimes when it's right there in front of you, you feel like you should do more and some of the things we've already gotten we take for granted. "That's the thing about golf, our season is so long and there's really not much time to relax, and even the off-season goes by so fast. There's not much time to sit on that thought, but I'm pretty sure that he wanted to win the US Open. "It's the same, we're greedy in that sense, like nothing will fulfill us fully until we're done and I don't think that's a bad way of putting it, I think that's the reason why we play and that's why he's at his level because of his competitiveness." The 36-year-old has gone on record, hinting that his come down after finally winning the Masters has been a tricky concept to grapple with, as his weekend at Oakmont was punctuated with outbursts. “Look, I climbed my Everest in April, and I think after you do something like that, you’ve got to make your way back down, and you’ve got to look for another mountain to climb,” he said. Avoiding the media and episodes where he threw his club on the 12th hole and smashed up the 17th hole's tee-box marker were another point of contention for some. ESPN's Scott Van Pelt, speaking on SVPod with Stanford Steve podcast, said that he was "baffled" by McIlroy's behaviour and that he seems "p****d off at everyone". Former professional and Sky Sports commentator Paul McGinley also weighed in. "I think Rory's better than that," McGinley said after McIlroy's fit of rage on the 17th at Oakmont. "Either not talking to the media or not giving a press conference like that doesn't serve him fairly or rightly for the kind of person that he is. He looks fed up to me. He's not himself. This is not normal."
