Here is Wie making what I believe is the infamous drop.
According to Rule 20-2: "A ball to be dropped under the Rules must be dropped by the player himself. He must stand erect, hold the ball at shoulder height and arm’s length and drop it. If a ball is dropped by any other person or in any other manner and the error is not corrected as provided in Rule 20-6, the player incurs a penalty of one stroke."
Reader Blue Blazer and other readers have pointed out that they noticed the almost waist-high drop as it was happening, and thought to themselves that Wie's dropping methodology left a lot to be desired. Hard to say definitively from the photo if she's at waist level, but it appears she's somewhere between the shoulder and waist.
Just something she might want to correct since her future ball drops will be closely scrutinized.
