Yup. Unfortunately the large, power-hitting, slower-running first baseman is a staple in this game. I don't really see it changing much.
I agree with you.
But if a team has a roster makeup that can afford a tall, lanky, quick and agile 1B with a great glove?
That is a HUGE advantage. Especially if your opponent has a few lefty slappers that like to drag bunt down the 1B line....
BUT... that wiry first basewoman better also rake on offense.
