What happened: Colorado's fifth-round pick Tyler Putnam is signing with the Rockies rather than honoring his commitment to Tennessee, according to Troy Renck. The 18-year-old right-hander had been seen as a genuine college-or-pro decision heading into the deadline.
Why it matters: Landing a Day 2 arm away from a Power Five commitment adds depth to Colorado's farm system as the front office leans on the draft to rebuild pitching depth. It follows a run of roster-building moves for a Rockies club overhauling its player development approach this year.
By the numbers: Putnam was Colorado's fifth-round selection and had been committed to the University of Tennessee before signing with the Rockies.
What to watch: Putnam now joins Colorado's farm system, with an assignment to a minor league affiliate to follow.
