Sophomore studs. (Spotlight).

Second-year players are about as easy to explain as computational aerodynamics--or egg substitute. To compile a list of the best second-year players, you've got to have some guidelines. Setting a number of innings or games played doesn't work. Although this is Reds outfielder Adam Dunn's second full season in the majors, he has played in parts of three.
