The Rockies shut Chacin down without having thrown a bullpen session this spring. It turned out Chacin's shoulder began hurting when he tried to throw off a mound before Spring Training. While he is improving, it's almost a certainty he will begin the regular season on the 15-day disabled list.
"I'm thinking about the long term, not rushing and getting set back," Chacin said.
