Headley is under team control for a couple more years.
Ask yourself the question: "Does that mean Angels keep Callaspo all that time?"
Caleb Cowart is in High-A ball and he is the lone 3B prospect yet there is no guarantee against injury or even being over his head as he goes to AA.
Callaspo is about 6" shorter than Headley...laugh all you want but this is an important stat for getting to balls around 3B, Callaspo misses many grounders by just a few inches...with Headley at 3B those balls would be ROUTINE PLAYS.
Headley is a better glove than Callaspo all around and a better hitter. A HUGE improvement.
To go with Callaspo for this season and into the future is bad judgment especially with a payroll like this. Counterproductive.
Short guys DO NOT RULE at the corner infield positions...a fact of life.
