Right-hander Jhoulys Chacin, who is slated to start for Colorado on opening day, has been scratched from a split-squad start against the Texas Rangers due to back spasms.
Chacin pitched for Venezuela in the World Baseball Classic and has been limited to 4 1-3 innings in three Cactus League starts this spring. He reported the back problems on Thursday and the Rockies decided to start Tyler Chatwood against the Rangers on Friday.
Rockies manager Walt Weiss announced on Tuesday that Chacin will start the April 1 opener in Milwaukee. Chacin was 3-5 with a 4.43 ERA in 14 starts last year, when his season was cut short by a pectoral muscle injury.
