Because he's been doing individual workouts at Great American Ballpark since May, Castillo is confident that he can ramp up quickly for Opening day, Mark Sheldon of MLB.com reports. "Right now, because I've been here such a long time and doing all of my bullpen sessions, I think I could go out and pitch 6-7 innings," Castillo said Saturday via translator Jorge Merlos on a Zoom call. "That's how good I feel right now. I'm perfectly OK to do so."

But Castillo appears to be well-positioned for the beginning of the season.
