Just saw an interesting stat. In 1997 Tiger hit 55 greens, or 76.4% GIR. This year he hit 58 greens, or 81%. That's despite averaging 29 yards less off the tee (294 vs 323).
So even though he hit it far shorter this year... had longer clubs into the greens... and was playing a much tighter, longer course, his tee-to-green game looks stronger even than when he blew the field away by 12 strokes (this year he won by 1). Suggests...
a) he may have struck the ball better than ever, at least at the Masters, and
b) the field is far closer to him now that it was back then. If so one reason for this is probably the huge increase in driving distance. In 1997 Tiger led the 2nd-longest hitter by 25 yards per drive. This year he trailed the leader by about 20 yards.
Other interesting stat: compared to 1997 we can trace the entire difference in his scoring to the par 5s. In 1997, he played them 13 under. This year he played them 8 under. Play the par 5s in 13 under this year, and he again shoots 270. Shows the difference when you hit wedges and short irons on your second shots, as he did in '97, against middle irons or even fairway metals, as he did in 2019.
Looked to me like Tiger repeatedly grazed the cup this year at Augusta. He seemed to roll the putts well, but tons just didn't quite fall. Makes me wonder what he might score, if more of those putts start dropping.
