Hole #14 at Oakmont, I've driven the ball about 10 yds right of the fairway into 40-50% 2nd cut rough, the hole is 98 yds away, 2 ft down with 20 yds of green in front, no wind. I hit a PW (Nike V-forged, L85, 115 yds) full shot, 100% power, dinged, bottom of spin dot lightly nudging the lie, expecting the shot to go 85-90 yds and (hopefully) roll close to the hole. Instead, it hits a low mound at 40 yds, takes a big bounce, & lands another 14 yds away for a total of 54 yds. Anyone want to hazard a guess as to why this didn't work & what I should have done differently? Thank you.
