Rockies sign Mike Dunn to 3-year, $19 million deal

The Rockies have reached a 3-year, $19 million deal with lefty reliever Mike Dunn, as first reported by Bob Nightengale of USA Today. The deal reportedly includes a $6 million vesting/club option for a fourth season.

Colorado has been uncharacteristically aggressive on the free-agent market this winter, signing Ian Desmond to a 5-year, $70 million contract earlier in the week. The Rockies were known to be looking for bullpen help from the outset of the offseason, and were a contender for Mark Melancon before he landed a 4-year deal with San Francisco.

Dunn, 31, joins Jake McGee and Chris Rusin as lefties in the Rockies’ bullpen mix ahead of closer Adam Ottavino. Colorado’s bullpen sported a league-high 5.13 ERA last season, making it a priority for the club this offseason. Dunn will replace free-agent lefty Boone Logan, who is expected to sign elsewhere after completing a 3-year deal with the Rox.

Dunn was solid in his sixth and final season with the Marlins in 2016, posting a 3.40 ERA and 8.1 K/9 in 42.1 innings of work. He is the owner of a career 3.54 ERA in 351 major-league innings with the Yankees (2009), Braves (2010) and Marlins (2011-16).
