CF is "easier" for a couple of reasons - you have fewer catches at the wall because of the depth, the ball tails less when it's hit up the middle, and you can see the pitch and swing better. The issue is that in most parks speed (to the ball, not always the same thing!) is more important than any of that so whoever is fastest plays CF. But Yankee Stadium is small so you put Willi in CF. I have no arg with him being in CF if you are going to put him in the OF. It's playing him in the OF at all. He's got a middle infielder's bat and a DH's glove. I get it, every once in a while he starts looking like a hitter, but it turns out to be fool's gold every time. He never sustains it. At this point I'm not going to believe it until he does it for 200 AB or so - preferable at AAA.
