With the 23rd overall pick, the Marlins have selected:
Christian Yelich, OF, Westlake HS (CA)
A lot of people think Yelich is going to end up at first base long-term, but the Marlins drafted him to play the outfield, as he runs pretty well. He doesn't hit for a lot of power, and he's unlikely to ever be known as a slugger, as he's drawn comparisons to James Loney and Casey Kotchman. The key, then, will be to make consistent contact and know which pitches to lay off. There's an outside chance that Yelich ends up in center, which would boost his profile. As is, he's a low-ceiling player with a peak around or slightly above league-average.
