Re: Top defensive plays you've seen
All time favorite defensive play: Bo Jackson throws out Harold Reynolds
All time favorite defensive play by a Red (seconded by Larkin): Eric Davis throws out Bobby Bonilla in the 1990 playoffs
All time best defensive play I've seen in person: Dave Parker making a throw out at home in the mid-1980s, then leading off the next inning with a home run. Sorry no video or details. I was a teenager at the time.
Sabermetrics can be boiled down to this simple truism: A batter's goal is to extend the inning. Extend enough innings and you're going to score runs. Extend more innings than your opponent and you're going to score more runs than him.
