All the stats on the back of his baseball card count. But if you are trying to use his 2013 season at age 23 to forecast what's to come, I think he (more than most) deserves a closer look. I've posted this before, but it gives me comfort to review it again. By my reading of his game log, there was a six week stretch starting in late April where his OPS was almost .700. Not bad for that age. Then he got hurt and was out three weeks. When he came back, he seemed to pick up where he left off and posted OPS above .800 for a couple of weeks. After the All Star break he was really terrible at bat, and I believe it was said he had some physical issues again sometime before being sent to AAA after July. Because he had been clearly getting himself out, the first two weeks in April, and then had a bizarre week right after that where his OBP was .476 based on top of a .167 BA, presumably having adjusted to the pitchers' approach to him, the start and end of his season combined for horrifying numbers. If that's cherry picking, so be it, but the Small Sample Size of 29 games where he stunk was smaller than the Small Sample Size of 52 games where he was a useful major league player. He still, to me, has fantastic promise.
