Here is an excerpt:
Chacin has split time between starter and reliever in the big leagues in 2010. As a starter, he has struck out 9.3 batters per nine innings with a 2.18 K/BB rate. As a reliever, Chacin has a K/9 rate of 12.7 and a K/BB rate of 3.75. So he has all the skills of a solid starter in 2011, and in the offchance that the Rockies need a closer, he could fill in nicely there as well.
