The Pronk Shift

The Pronk Shift is a baseball defensive maneuver created by Tampa Bay Devil Rays manager Joe Maddon, as a way to deal with Travis Hafner (nicknamed "Pronk.")

On April 21, 2007, with Hafner in the midst of a torrid power tear, Maddon shifted his defense as follows (photo by Manny Stiles):

• Third baseman Akinori Iwamura moved behind second.
• Shortstop Ben Zobrist went to deep left field.
• The outfield shifted deep and to the right.
• Second baseman B.J. Upton moved to shallow right field.

In Hafner's first at bat against the shift, the defensive maneuver paid off, as Hafner hit a line drive to deep left-center -- right at the newly-positioned Carl Crawford.

A form of it was first used in 1946 against Ted Williams.
