One of the most important things that separates a future starter and reliever is the number of pitches the pitcher can throw. A reliever only needs one or two dominating pitches because it's unlikely he'll see the same batter in a game more than once. A starter doesn't have that luxury and needs to have several pitches in order to keep the hitters off balance. A sharply thrown slider might strikeout a hitter the first time, but major league hitters learn quickly and the next time they see that slider they may hit it for a home run. Thus future starters usually command around 4 pitches. Rarely do you see a pitcher like Chien-Ming Wang who more or less gets by with only two pitches simply because his sinker was so dominant.
