In the short time that I've seen him, I have to say I've been disappointed in his game. I recognize that Mike Trout struggled in his first go-round, so Arcia is hardly a lost cause, but I was expecting more. His shortstop play is supposed to be his calling card, but last year seemed pretty ordinary to my eyes. He didn't look all that rangy. His arm was strong and accurate, but not eye-popping, at least to me. His hitting stats were worthy of hitting no higher than 7th or 8th. He didn't blaze on the basepaths. That said, he's young, cheap and under team control for a long time. He could still develop into a star. But his struggles remind us that prospects aren't sure things.
