Reds make roster moves and secure win against Rockies.
The Cincinnati Reds have officially called up left-handed pitcher Brandon Williamson to make his big league debut as the team's starting pitcher in Colorado. To activate Williamson, the Reds optioned right-handed reliever Alan Busenitz back to Triple-A Louisville. Williamson's debut comes with concerns as Coors Field is known for home runs and a large outfield. Williamson has been inconsistent this season, struggling to throw strikes and giving up a lot of home runs.
