11:50am: The Denver Post reports that Chacin will join the Rockies tomorrow as a reliever. Here's Baseball America's take on the young pitcher.
THURSDAY, 11:46am: Ken Rosenthal of FOX Sports reports that the Rockies pulled Chacin from last night's start to promote him to the majors, possibly as a reliever. The right-hander has allowed 87 hits and walked 35 in 103.1 innings at AA, striking out 86.
WEDNESDAY, 11:42pm: According to Kevin Goldstein of Baseball Prospectus, the Rockies pulled pitching prospect Jhoulys Chacin from his start tonight "as a precaution for possible, future organizational moves." Chacin tossed one inning for the Double A Tulsa Drillers, tallying just nine pitches.
Chacin, a 21 year-old righty, ranks as the Rockies' top prospect according to Baseball America. BA wrote in praise of his fastball and changeup in their latest Handbook.
Thinking about a possible Roy Halladay connection? Rockies GM Dan O'Dowd didn't seem keen on the idea, talking to MLB.com this morning. Elsewhere in the rumor mill, SI.com's Jon Heyman recently linked Colorado to a slew of relievers (including Chad Qualls and George Sherrill).
