Ramirez (forearm) was transferred to the 60-day DL on Friday, Jeff Fletcher of the Orange County Register reports.
This move eliminates any hope for a late-season return. After spending 2016 in the bullpen between Cincinnati and Anaheim, Ramirez found success in the rotation earlier this season thanks in large part to an altered pitch mix. Assuming he's back to full health by spring training, Ramirez should compete for a starting role.
