Stretching... guaranteed...100%
You need to stay down and through the ball for that 10 inches during impact..
Without even seeing your swing my guess is you now come across the ball and/or hit more shots thin and to the right because you are losing flexibility.. Decreasing distance...
Stretch, stretch, stretch
i’ve never stretched. maybe i should start.
BTW...thanx...small short stretching...(I stay away from back stretches - I have a whacked back)now tickling 250+ and my runout draw is back.
