Sandy Lyle is on course in his second round after shooting a 76 on Thursday, but earlier in the week I caught up with him for a chat about his famous Masters win in 1988 and THAT seven iron.
"Physically, I was getting very tired. I'd had a gruelling week the week before when I won a play-off in Greensboro, and then all the media attention at the Masters was quite hectic. Leading for two days and then losing the lead on the back nine before getting a share of it back again going to the very last hole, it was a real roller coaster. It was digging about as deep as you ever want to go, just trying to keep your momentum and enjoy the moment.
"On the 18th tee I felt I had to put myself in position where I could hit a second shot, even if it was 190 yards. Gambling and cutting a drive to put it further up the fairway was too risky. My plan was to hit it at the bunkers but keep it short. I was only a couple of yards away from being perfect. It was quite a struggle with my emotions. My first thought was, 'oh no, not another roller coaster'. I'd just birdied 16 and made a good par on 17 so I was on a high, within reason, and now I'm back in the doldrums again in the bunker.
"To my delight the ball was lying better than I thought it would be. To me it wasn't that hard a shot, but everyone else seemed to think it was unbelievable. I was comfortable picking it off the surface with a seven iron and tapped in a little 15fter for birdie. It was a dream come true."
