The idea for this post came about from reports last week that the Yankees were considering flipping Brett Gardner and Curtis Granderson on defense, with Gardner taking over in center and Granderson shifting to left field. Of course, Granderson had his forearm broken by a J.A. Happ fastball yesterday, so now the decision has been made for the Yankees, as Gardner will start the season in center field. However, the Yankees will still have to decide what to do when Granderson returns from the DL in May, and they aren’t the only team looking at pairing a couple of center fielder in their outfield this year.
The Angels are shifting Mike Trout to left field because they’re going to give Peter Bourjos a chance to play regularly. The Indians are moving Michael Brantley to left field because they signed Michael Bourn. The A’s are going to use Chris Young all over the outfield because they have Coco Crisp already. In some cases — Trout and Bourjos, for instance — the defensive excellence of both means that there’s probably no wrong answer, as either could play center field and have it look like the right decision. But, in New York, the question was a little more interesting, as Gardner is generally considered to be a better defensive player, and flipping their positions was a consideration based upon improving the overall defensive quality of the Yankees outfield.
It makes sense, after all, to have your best defenders play where the ball is going to be hit the most often, but how much does it actually matter? What’s the magnitude of the difference between having Gardner in center and Granderson in left versus the alignment the Yankees have run out the last few years?
