Rockies right-hander Jhoulys Chacin struggled in his last outing, after suffering a finger blister in the outing before that. Quite simply, the Rockies expect Chacin to be efficient today against the Reds.

Also, the Rockies have placed Jordan Pacheco on today’s roster as a backup infielder. Pacheco, a right-handed hitting utility man whose bat has impressed the Rockies,  has peformed well at catcher throughout camp. Pacheco, an infielder in college, has made some good plays at third base but he is still considered a work in progress. At the end of the Rockies’ batting practice, Pacheco spent extra time with infield coach Rich Dauer fielding balls off the bat and working on his stance and movement.
