The exact opposite is actually happening though. Fewer outs will be recorded by having the contact play on than by not having the contact play on. It's easier to throw to first for the force out than it is to throw home for the tag/rundown. I think you are assuming everyone is blinded by their aversion to making an out at home when in reality, the confusion is regarding how you are framing the question. I asked you to provide the assumed base/out situations. You came back with the run difference between to base situations. The part that you appear to be ignoring in your analysis is the part that I don't like about the contact play. A contact play forces a batter to swing at a pitch that he otherwise may not have. That obviously negatively impacts the odds of that swing resulting in good contact and hence, a non-out. That must be considered in any analysis of the contact play. Am I misunderstanding something? Yes, I think you are. I'm not talking about the squeeze play (safety/suicide or otherwise) The batter has nothing to do with the contact play. It's NOT a hit and run. He just takes his AB as he normally would. What it DOES do, is allow the runner on third to get a gigantic lead at third base and immediate take off for home as soon as the ball hits the ground. He freezes on a line drive/fly ball/ etc. If the contact play is not on, he has to take a smaller lead at third, as if the ball is hit hard at the third baseman or SS he has to get back to the bag before they do. With the play on, he can be as far away from the bag as the third baseman (or a step farther) and score that many more times on ground balls that he wouldn't be able to if he were 5 feet closer to the bag. There is very, very little downside to having the contact play on, at least once you get over the trauma of making an out at the plate. Also, I agree that very few times the batter ends up at second base on the contact play. That is more due to poor awareness, coaching, execution and understanding of baserunning than a strategic thing. Obviously if Prince is at the plate and Johnny Estrada is at third, that situation won't happen (Although it still might be advantageous to run the contact play). But the current team has A LOT of speed and athleticism. They should be able to run it more effectively than they do (even still, I think it's been more positive than negative the last couple of years).
