Re: Most amazing baseball feat.
Live: I was at the game where Pete got hit 4192. Runner up would be the game where Dave Parker threw out a runner at home, then led off the bottom half of the inning with a home run. Honorable mention would be Larkin hit 2 home runs in a game on his way to hitting 5 home runs over 2 consecutive games. A note: friends had an extra ticket to see Tom Browning pitched Reds game in Sept. 1988, but they didn't ask because I was already at work for the evening. Besides it was raining so it wasn't clear whether the game would even go off...
TV: Has to be 1990 playoffs, Eric Davis throws out Bobby Bonilla at 3rd base. From center field. After running over from left to back up the play. To this day that's the best Reds defensive play I've ever seen on TV. Others I may or may not have seen on TV (don't really remember): Bo Jackson throws out Harold Reynolds at home; Jack Morris throws a no-hitter.
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.
