I think the game would be much livelier and more interesting if so many innings weren't pitchers' duels.
Suppose for the first 6 innings the opposing team got to pick which player would be the pitcher. (Nobody could be required to pitch more than 2 innings if they and their coach disagreed.)
Each position player would have to be more of a utility player, since he'd never know from inning to inning where he'd be. Except for the late inning closers, of course--that's still enough of a tradition that we should probably keep it.
This opens more opportunities for strategy: who do you pick as pitcher, and how do you defend against losing (e.g.) your best catcher to the pitcher role for an inning?
And there'd almost certainly be more hits, more infield and outfield play--a livelier game. What's not to like?
She doesn't like the idea.
