Greg Holland has yet to pitch in an exhibition game, but the Colorado Rockies remain optimistic that he'll be ready for the start of the regular season.

Holland, who signed with the Rockies in free agency, won't make his Cactus League debut until next week at the earliest. He underwent Tommy John surgery in 2015.

"As a competitor, you want to be out there. If you can't, it's demoralizing," Holland, 31, said. "But you have to understand that there is a right way and there is a science behind this. You have to stay patient with it, as hard as it is. I think I have done a pretty good job of that."
