Aaron Cook was given a nice contract in the off season and many questioned why the Rockies did it. The answer is that the Rockies felt that if Cook could stay healthy that he would be a good pitcher for them. They seem to have been right as he has been by far the best starting pitcher for the Rockies this season. Cook has started 7 games for the Rockies this year and he is 5-1 with a 2.40 ERA and a 1.15 WHIP. As long as Cook keeps the ball down he will continue to be effective this season.
