Concern from umpires about being able to properly identify whether Boston Red Sox pitcher David Price is throwing from a full wind-up or a set position has resulted in a new rule this season.
Call it the “Price Rule.”
The rule states that pitchers are now required to alert the umpire of their pitching delivery when there is a runner on third base. As ESPN’s Buster Olney explains, “If a pitcher takes the rubber and his back foot is parallel to the mound and his other foot is in front, it is assumed he is in the set position and he will stop.
