Erratic, yes, but hardly overrated.
He never should've put himself in that position yesterday, but he did...and he bailed himself out with exactly what he needed on that approach shot at 18. A 12-footer is no gimmie, even for Tiger, but to leave it hole-high, he had the perfect line to sink the tying putt.
Overall, though, he's going to have to play much better today - especially on the front 9 - if he hopes to beat Rocco, aka Mr. Steady.
