Rockies' Charlie Blackmon: Scratched Saturday with back tightness

Blackmon was a late scratch Saturday due to back tightness, ROOT Sports' Jenny Cavnar reports.

This injury came out of nowhere, and it will allow rookie Raimel Tapia to make his first career start while also leading off against Arizona on Saturday. Blackmon should be considered day-to-day for now, but if he were to miss more time, Tapia would be ready to fill in.
