Of course Peralta could play third base as a hedge against an A-Rod suspension. And he can play shortstop in the case of a Jeter-is-hurt/Jeter-is-old/Ryan-can’t-hit combo. All of which are fairly likely.
If the Yankees are in on Peralta, you have to figure they’re in on Stephen Drew too, and would go for one or the other. Or maybe their whole offseason plan hinges on signing every single possible shortstop and letting God sort it out.
It’s always a bit deceiving to see offseason workout photos of players who are said to be getting into great shape because guys in those pics are wearing compression shirts and crap and we’re used to seeing them in baseball uniforms. I remember pics of Miguel Cabrera and David Ortiz in the offseason looking svelte, only to see them in uniform come spring as their familiar beefy selves. Uniforms are often loose and billowy and the players wear a couple of layers when they’re suited up, so at least visually speaking it’s better to compare apples to apples.
