I'm doing some research myself on this topic for a possible story, but thought I'd reach out to people whose memory or research skills are better than mine. I'm trying to find Twins players who we were sure would be on the Opening Day roster, but ended up hurt in spring training. I'd like to go back at least the last five years. Here's what I have so far.
2018 - Ervin Santana
2017 - Trevor May, JT Chargois, maybe Kennys Vargas
2016 - ???
2015 - Ervin Santana suspension,
2014 - ???
2013 - Scott Diamond? Anthony Swarzak
