Ultimately, I think it's called luck until there's data to define the successful situation and then that data is being used in the game to create a successful outcome. For example, if a batter hits a line drive and a fielder is standing right there to get it, we might call that lucky. If that line drive was hit into an extreme shift, then it's considered to be sound strategy to move the fielders into the place the batter's most likely to hit the ball. The Sox error on the Mauer bunt was luck. If Molitor knew that Sandoval is more likely to drop the ball on a throw from the catcher at that time of day, and then called for the bunt to try to force an error, well, that's crazy, but if somehow that was supported by data, it wouldn't be luck so much as a strategy. Molitor spoke about the bunt after the game and sounded almost upset about the outcome. It was not a good bunt by Mauer, so he probably wanted his players to execute the play. Molitor did call for the sacrifice, he wanted to get the guys in a position to score. It worked out, and the miscue seemed to breed more miscues. Again, not actually related events, but the story you tell your kids makes the fish get bigger every year. The Twins are lucky because they can't explain how they are doing it, and it is not a repeatable strategy that is making them successful. If they could figure out how they could get Santana to hit, or to incorporate the trio (Arcia, Vargas, Pinto) back into the middle of the lineup without sacrificing too much on defense, I think they could flip the switch from lucky to good.
