Jorge De La Rosa took another step in what has been a steady recovery from Tommy John surgery when he began mixing his changeup with his fastball while throwing a bullpen session at the Rockies' spring training complex in Scottsdale, Ariz.
De La Rosa threw 15 fastballs followed by five changeups and after a brief rest threw the same three to one ratio of fastballs to changeups but mixed the pitches. He was scheduled to have the same pattern in his next bullpen session and then was to rest from pitching for a week.
Beginning Feb. 10, De La Rosa will resume pitching and will gradually work up to 50 pitches before facing hitters, which assuming no setbacks is scheduled to occur in the middle of March.
When camp breaks, De La Rosa will stay in extended spring training...
