After putting together impressive numbers in the minor leagues, Trevor Bauer, the third overall pick in the 2011 MLB draft, made his major league debut for the Arizona Diamondbacks. He was decent in his first start as he went four innings, giving up two runs on five hits while striking out three.
One of the reasons that Bauer was able to reach the big leagues so quickly was because of the fact that he was fairly polished. In fact, Bauer may have better stuff than a number of MLB aces.
Bauer throws a number of different pitches which allows him to keep hitters off-balance throughout the game (h/t Andrew Pentis, milb.com). Some pitches have been developed much more than others, but there is no denying that Bauer has outstanding stuff.
For the sake of this article, an ace will be defined as a team's No. 1 starter or a pitcher that is capable of being a No. 1 starter on most teams in the majors.
