Changes are in the offing for the Rockies’ roster as they opened the so-called second half of the season Friday. A number of moves are pending, and those moves will directly lead to other roster decisions: — Left fielder and first baseman Ian Desmond worked out Thursday and passed all of the tests. He remained on the 10-day disabled list Friday, but should be close to returning from his right calf strain that put him on the DL on July 3. “You might see him sooner than you might think,” Black said when asked about Desmond’s progress, an indication that Desmond will not need to go out on a minor-league rehab assignment. “He had a good day yesterday in Denver, working out. We ran him through a number of things that he passed. He hit and ran the bases.”
