The Colorado Rockies believe starting pitcher Jhoulys Chacin can bounce back from an injury-marred 2012 season, and are willing to make a multi-year bet that they’re right. Chacin and the Rockies agreed on a two-year deal worth $6.5 million over the weekend. The 25 year-old right-hander missed over three months with a shoulder injury last season, and went 3-5 with a 4.43 ERA in 14 starts after being one of Colorado’s most consistent starters the previous two years.
