In 2012, the Rockies had one of the worst pitching staffs in the history of the MLB. Not one of their starters had an ERA under 4.43–Jhoulys Chacin had that mark pitching in just 14 games. Chacin has had his struggles in the past with walks as he led the league with 87 base-on-balls his last full season in 2011–this number has to dwindle in order for the Rockies to even remotely compete.
Chachin, who turns 25-years-old this season, will be the focus of a Rockies rotation that has to perform better in 2013.
After Chacin, the Rockies will throw lefty Jorge De La Rosa who pitched in just three games all of last season. De La Rosa has had success in years prior, but he hasn’t started more than 20 games in a season since 2009. This is a guy who is just four seasons removed from winning 16 games, but he was not a part of the NL pennant winning team in 2007.
Coors Field has been home to some of the worst teams in MLB history as the Rockies have finished last or second to last in the NL West 15 out of the last 20 years. In order for the club to buck that trend they will need production from their top-tier starters in De La Rosa and Chacin.
