The Astros won't become a top offense overnight, so if the Astros are going to be competitive this season, the pitching will need to be a key component this season. The good news is that the Astros do have the pieces to be a top flight rotation.
Brett Myers had a bounce back year in 2010 that no one expected and Wandy Rodriguez started off slow but pitched very well down the stretch. J.A. Happ was the key piece the Astros got in the Roy Oswalt trade, and Bud Norris had an up-and-down year but showed flashes of being a good pitcher.
Nelson Figueroa, who is the favorite to win the final spot in the rotation, had an ERA under 3.50 in his final 10 starts. However, he will have to fight off top prospect Jordan Lyles for that final spot in the rotation.
The Astros have enough talent in the rotation, as well as the bullpen, to keep the Astros competitive in 2011.
