Short game is a huge stroke saver for sure. A friend of mine used to be a 110 shooter - he has a decent tee game and strikes his irons reasonably well, but get him around the green and he'd waste at least 4-5 strokes a hole blading/duffing chips and 3 or 4 putting. He has made a lot of effort to improve his short game, and he now pretty routinely shoots in the mid-90s - today he shot a 94, and he broke 90 for his first time ever last week.I played this morning and walked away with a 101. Even though my lessons have been all focused on irons, I’m seeing the most benefit with my driver. I didn’t have a single penalty from the tee box today. I sliced two drives, but even those were in play. Between driver and my Crossover, I probably hit five shots that would have been the best shot of any other round I’ve played (including a 285 yard drive).
What has become very apparent is that I’m never going to score better until I improve my short game DRAMATICALLY. The most glaring example of this was on 18. It’s a 500 yard par 5. I hit my drive about 250 to the middle of the fairway. My second shot was with my Crossover, and I was again in the middle about 30-40 yards out. I ended up with a double bogey. That was the recipe much of the day. I just have no clue what I’m doing with a wedge or putter in my hands.
When he's close to the green, he now focuses on one thing only - get.the.ball.on.the.green. Make your next shot a putt, even if it's a long one. Don't be cute and try to hunt pins or hit creative touch shots - get the ball on the green by whatever means is easiest. Bump and run, long chutt with a hybrid, putter from off the green - whatever. Learn one or two simple shots for around the green, practice them and get good at them, and leave all the fancy stuff for later - you don't need to be messing around with flop shots, low spinners, trying to back the ball up, etc. Sure, those shots look cool when you pull them off - but they can also fail horribly and blow up your scorecard in a hurry.
The difference between shooting 95 and 110 is less than one stroke per hole. If you leave a lot of shots out there from around the green, simplifying and improving your short game is a quick and easy way to bring your scores down pretty quickly. Not all of us can drive the ball 300 yards, but all of us can hit a 5-15 yard chip shot and get it on the green.
