a 16 year old shot 61 in a US Open Qualifier....
PGA Tour players have been great their entire lives, and practice and play nearly every day.
In addition, more great athletes are choosing golf at an early age-and working equally hard that by the time they reach the Tour they are incredibly skilled and fearless(especially those who come up via web.com where -24 might get you 3rd place.
Throw in the last 18 years of ProV1, Trackman, better Coaching,better physical and mental training,driver and now iron faces that rebound at impact and optimization and you've got a formula for exponential equipment.
In short these guys are good
The ONLY way for a winning score to be somewhere near par is to dry the greens out to nothing, run them at 13 plus(not 15 like Mike Davis states) tuck the pins, carve par to 70, grow the rough, and tip the tees out.
Interestingly, there are a variety of ways to drive scores higher (Blind shots, greens that run away) that wouldn't impact the average guy as much as a pro but sadly no one has the balls to do that anymore.
It always cracks me up when people say how great it is that golfers use the "same" equipment as pros, and that bifurcation would change that.
Yet the average player would NEVER see, want to , or be allowed to play a course in "somewhere around par winning" tournament condition with their tees and pins,water everywhere(TPC) and the greens struggling for survival.
For those who enjoy seeing higher scores, wouldn't it simply be easier to bifurcate equipment rather EVERY single course being bifurcated for events?
