Rockies RHP Chacin scratched with back spasms

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.
