Chacin takes step toward bullpen sessions

Chacin takes step toward bullpen sessions

SCOTTSDALE, Ariz. -- Rockies right-handed pitcher Jhoulys Chacin, shut down Sunday because of a strain and inflammation in his throwing shoulder, began using resistance bands Friday morning and hoped to resume light throwing in a couple of days.

It is still not clear when Chacin will be able to start throwing bullpens. The team had to shut him down because he would experience pain once he began throwing in earnest. He has not thrown a bullpen session since arriving at Salt River Fields at Talking Stick.

Friday's exercise represented progress, as it gave Chacin the opportunity to build much-needed strength. However, because it is not clear when he will be able to throw bullpens or appear in games, it remains in doubt whether he will be ready in time for the opening of the regular season. The Rockies have said they will not rush him. The team entered Spring Training fostering competition for Juan Nicasio for the No. 5 rotation spot, and manager Walt Weiss is approaching Spring Training as if the Rockies need to fill Chacin's spot to start the season.
