A lineup filled with plodding veteran sluggers was consistently done in by the shift, and the team’s unathletic infield didn’t take easily to the concept on defense. Oh, how times have changed.

Now, the Yankees are actually one of the teams least-shifted against in the majors. Not only that, but it’s a pivotal part of the team’s defensive strategy.
