Random thoughts:
Tony LaRussa did not know he could have the last batter from the 9th as the runner on second base to start the Sox' half of the 10th. Old guy, new rule. From watching a game, I learned that if the batter who made that last out is then removed from the game, you're allowed to use the previous batter to start your 10th inning on second. I hadn't thought about that scenario. I suppose you could also use the player who is going to be placed in the removed player's spot in the lineup, most likely a pitcher.
I looked up what the fewest number of pitches is for a complete game. The record is 58, set in 1944. Greg Maddux is, I think, 7th on that list, in a game he pitched for the Braves at Wrigley.
Someone had a "factoid" in the questions that pop up after a search about the fewest number of pitches possible in a complete game. This is entirely theoretical, not at all probable. The answer is 9, yes, nine!
Here's the (incomplete) explanation (my summary):
1st pitch: triple
before the next pitch, runner attempts to steal home
2nd batter interferes with the catcher: 1st out
1st batter/runner is declared out also
That's where it stopped, and I couldn't click on anything to show me the rest. I figure that the only way to get the third out without a pitch being thrown is if the 4th batter (or later) then comes up to bat out of order. He's out. Edit: Not true. Correct batter can enter the game and inherit the count. So, I’m not sure how a third out would be called.
Of course, to duplicate this for 9 straight innings is impossible. As I said, it's just theoretical. Now, the answer in a less mind-bending scenario would be 27 pitches. That would require every batter to swing at the first pitch, unless he was hit by it. No one could get a hit or be hit by a pitch after there were two outs. After every hit (or hit batter), the next batter would have to hit into a double play. Errors are also only allowed with less than two outs, and the subsequent double play could take several forms, depending on where the previous batter stopped on the base path. With the new intentional walk rule, you could (theoretically) have only 2 pitches per inning, 9 double plays, and only 18 pitches.
But only 58 pitches! That's just barely over an average of 2 pitches per batter! Why did those guys keep swinging??
