The Colorado Rockies announced that RHP Zach Agnos is starting today's game, a last-minute change from the previously scheduled starter.

The club's announcement offered no explanation for the switch, and the identity of the original starter — along with any reason for the change — remains unconfirmed.

What we don't know yet

Colorado's rotation has been in a state of flux. Kyle Freeland landed on the 15-day IL with a pinched nerve in his neck, a move that opened the door for No. 20 prospect Mason Adams to make his MLB debut against the Nationals earlier this week. With multiple moving parts in the pitching staff, Agnos stepping into today's slot is the latest development to monitor as the Rockies sort out who is available and when.

What exactly prompted the change to Agnos — whether it is roster-related, a precautionary move, or something else entirely — has not been disclosed.
