In the post round interview he's going to state the rain changed everything, caught a moist flyer from the fairway on 16 and grabbed the putt early on 17.
For those who thought Faldo wasn't awful... today's broadcast should prove otherwise. He's so terrible.
Though I agree with Faldouche about going for it in 2 on that long par 5. He's going to win the tourney by 10+ shots and he's got a legit chance at 59 and he laid up. Why? Just murder a fairway wood or hybrid and keep it a bit left then get up and down for birdie. Or get lucky and stop it on the green with a chance of an eagle.
