2014 Due to publishing agreements, the 2014 player comments and team essays are only available in the Baseball Prospectus 2014 book (available in hardcopy, e-book, and Kindle).
2013 If you like peripherals, then Dayton is your man. The Auburn grad and 11th-round 2010 pick started slowly for a big-program college senior, but the Marlins tweaked his mechanics and were rewarded with significantly improved control. Armed with the tandem of a plus fastball and slider, Dayton is now on the fast track to the majors and could make his debut before the end of the season. He has the stuff to push Michael Dunn for lefty setup work once he gets the call.
