What difference does it make what a coach is teaching their player, there is no requirement in the rules to slide EVER. Running the bases is not an act of interference and except for the strange interpretation of the rule NCAA has put out I know of no other rule set that would consider the play in question to be interference.Just a quick question for you, MTR... When you have a player steal a base, do you teach them to go into the base standing up? If they answer is "no", why on Earth would you have them go into 2nd base standing up on a double play? I want my runners to get to 2nd as quickly as possible and sliding is the quickest way.
