Big Play With Rob Stanger

WHO: Michael Campbell

WHAT: 30-yard greenside bunker shot to five feet

WHERE: Par-4 15th at Pinehurst

WHEN: Final round of U.S. Open

WHY
Campbell's compact swing was perfectly suited to this long sand shot from an uphill lie tight to the lip. The shorter swing helps Campbell focus on precision at the point of impact--hitting the ball an iota fat or thin could have cost him the title if it had led to a bogey or worse, instead of a miraculous par.

ROB'S TIP
To Go Long, Draw a Line in the Sand

Precise contact is particularly important on bunker shots. For short explosions the clubhead should hit the sand a bit behind the ball, but on longer shots you must make contact with the ball first. To become more precise at making contact, try the Line Drill. Draw a line in the sand and imagine your ball is resting on it. Take a practice swing, making sure that your divot starts on the line and goes forward. Move a few inches down the line and swing again. After four or five successful tries, place a ball on the line and swing through.
