Rory McIlroy was asked ahead of The Open if he agrees with the idea that “Trackman Golfers” don’t do well at Opens: “No, I wouldn't totally agree with that. I think that TrackMan or any launch monitor, it's a very useful tool. I think you can get too into the numbers, which then can be detrimental. I think, yeah, TrackMan can be very useful. It can be -- I think it can actually help you with the feel of your golf swing at times. “If you see a certain number on TrackMan, it gives you a feeling of what you need to do, so if you can sort of match up the number you see on the screen with a feel that you have in your golf swing, I actually think you can become more feel-based. “I use TrackMan a lot in season because I feel like it's hard to work on technical positions when you're just trying to manage your pattern through the course of the season. I use TrackMan where it's like, okay, my path's getting a little to the right, I've just got to feel like I swing more left. Or my face angle is getting a bit left and I've got to feel like I hold it a bit more square through impact, whatever it is. “To me, I actually feel like it's a great tool to use when your swing gets off a bit and you can sort of train your feels back into where they need to be.” @McIlroyRory @TheOpen @LukeKerrDineen
