6. Mike Leake, 23, Reds (+36 2/3). Reds GM Walt Jocketty targeted an increase of between 20 and 30 innings for Leake in 2010, but allowed him to slightly surpass that goal. Leake also made his minor-league debut this year, getting two tuneup games in Triple-A. Leake bears watching because he is not a prototypical workhorse. In two major league seasons, the 185-pound Leake is 14-5 in the first half and 6-8 in the second.
