To hone your short game skills, take one ball to the practice green, chip it to the hole then putt it out. You can play 9 or 18 “holes” this way.
Vary the position from which you chip, and be sure to hole out each putt.
By combining both your chipping and putting skills you are practicing what you will do on the course. You can either keep score yourself and try to beat your personal best, or compete with one of your golfing buddies in a matchplay format.
