Besides the Pearce and Eovaldi trades?
2017:
Signed Mitch Moreland to 2 year deal
Traded 3 marginal prospects for Addison Reed
Traded Shuan Anderson & G Santos for Nunez, who did great for us in '17.
Claimed Doug Fister off waivers
Signed Marcus Walden to minor league deal
2018:
Signed Ryan Brasier to minor league deal (did great)
Traded Quiroz for Brewer
Traded Deven Marrero for Josh Taylor
Signed Ryan Weber
2019:
Traded Blake Swihart for Marcus Wilson
Unlike small market teams, DD had mostly low draft picks, but did pretty good with them:
2016: Dalbec, Groome, Chatham, Shawaryn, K Hart
2017: Houck
2018: Casas (our #1 prospect), Ward, Duran, Feltman
2019: Lugo & Song
I'd say there were some decent "small market type" moves by DD.
The lack of any meaningful IFA signings hurt us badly.
