On 3/24/13, the Rays put the following shift on Kevin Youkilis of the Yankees.
I decided to the Batted Ball Location application to see how often he pulls the ball which would cause the Rays to put on such a shift. Dividing the field into fifths, here is how often he hit ground balls into each area:
89% of Youkilis’s batted balls went to the center to left side of the field. The extreme shift, especially against a right-henaded hitter, makes sense considering the heavy pull nature and the lack of speed from Youkilis.
