MLB just updated their prospect lists yesterday I do believe.
While Semien's first full season of pro ball coming out of Cal was interrupted by some injuries, there were some very encouraging signs, particularly his second-half production: .290/.392/.514. He's been inconsistent with his offensive game overall and needs to show he can do what he did in the second half of 2012 for an entire season. He has average arm strength and speed, and while he shows he can make the plays at short, that's another part of his game that's been up and down. He did see some time at second base and his future might be as a utility man, one who can punish left-handed pitching.
