The St. Louis Cardinals need a big bat. This big bat needs to be an authentic number-three or number-four batter. These impact bats affect the outcome of the game in more ways than at the plate.
How so? If we look back at the St. Louis Cardinals of past years, we see that batters such as Albert Pujols and Matt Holliday affected the game both with their bat and with the fear of their bat. This is the real threat of an impact bat.
Let me restate this directly: an impact bat brings more to a team via their threat than simply via their bat.
