Pick your spot and trust your swing—bunker aim challenge

Put 18 balls in a straight line in the sand. Make a second line of 18 balls. Lines should be 5 to 10 yards apart, balls in each line 1 foot apart.

Pick two flags on the green, 20 to 40 yards away. Each line aims for its own flag.

From the first line, hit 18 balls trying to land each one within 10 feet of the first flag.

Move to the second line, hit 18 balls trying to land each one within 10 feet of the second flag.

Draw two circles on the green around the hole: one with a 6-foot radius (birdie zone), one with a 15-foot radius (par zone).

Hit 36 sand shots: 18 shots trying for the small circle, 18 shots trying for the bigger circle.

Start at any pile. Hit one shot at a time, aiming for the zone you need.

After 18 shots at the small circle, switch to aiming at the big circle for the last 18 shots.

Count a shot as good if it stops in the target circle. Shots outside the big circle are misses.

On the green, mark 4 equal circles using string or tees. Each circle has a 6-foot (2 meter) radius.

Hit 36 sand shots. Hit 9 shots at each of the 4 circles.
