Offense is certainly important, and an issue for the Twins. But that's a lot tougher to fix than defense, and a run saved counts as much as a run scored.
Today's game is just an example.
Twins are down 5-2 in the 8th as I type. With just standard, to-be-expected MLB defense, it's 2-2. Mistakes and misplays are all too common, and in the context of MLB, they add up.
