I wouldn't say it was a full-out sprint, but yes there were plenty of times I'd almost make a game out of it. I wanted to beat the runner to my location (wherever that was on a particular ball) before he made it to first base. Did it always work? Probably not. And people talk about how it does do this and it doesn't do that, whatever. But I read this recently with regards to something else, but it makes sense here too... "You can't quantify on prevention."
