Chicago Cubs: Where Should Shortstop Starlin Castro Bat?

The hot bat of Starlin Castro has been one of the nice surprises to the Chicago Cubs and the rest of Major League baseball through the season's first month.

Castro, at the tender age of 21, has seemingly erased any doubt about a possible "sophomore slump" in his second year in the Windy City.

The question the Cubs must be asking is, "How high is his ceiling?"

Players as young as Castro generally don't sniff a major league ballpark until September, when rosters are expanded and teams do unofficial "tryouts" for next season.
