The one major weakness that the Colorado Rockies had last season was certainly their bullpen as they couldn’t close out games even when they had a big lead. Colorado is trying to fix that issue as they signed left-handed pitcher Mike Dunn to a 3-year/$19 million deal. Dunn has been a productive relief pitcher throughout his career and he had a solid 3.40 ERA with the Marlins last season. The Rockies aren’t really even sure who their closer will be next season, although the likely candidate for that role is Adam Ottavino. I don’t see Mike Dunn being the closer for Colorado, but he could be a good fill-in if needed. Dunn will likely be the much needed 8th inning setup man that the Rockies bullpen desperately needed. Dunn isn’t a great pitcher, but this signing is a success considering how difficult that it has been for the Rockies to find quality pitchers in free agency. Not many good pitchers want to sign with Colorado and risk the possibility of ruining their careers. Dunn gives the Rockies a proven relief pitcher and we’ll see if he can succeed while pitching at Coors Field.
