Veteran southpaw Mike Dunn announced that he is finished with his playing days, as Bob Nightengale of USA Today conveyed via Twitter. The 34-year-old says he’s ready to spend more time with his family.

Dunn just wrapped up a three-year deal with the Rockies that didn’t quite turn out as planned. The typically hard-throwing lefty lost velocity out of the gates in Colorado and never really found his footing. He struggled with injuries over the final two seasons of the pact and wasn’t effective when he was on the mound. All told, Dunn managed only 85 innings of 5.93 ERA ball with the Rox.

There were plenty of good seasons before that, of course. Dunn was long a valuable performer for the Marlins during a six-year stint. He worked to a 3.59 ERA with 9.8 K/9 and 4.1 BB/9 over 328 frames in Miami.

Add it all up, including Dunn’s early-career stints with the Yankees and Braves, and he threw 436 total innings in the bigs. He allowed an even 4.00 ERA for his career. As you might expect, Dunn was generally quite a bit more effective against opposing lefties, holding them to a .232/.315/.353 cumulative batting line.

MLBTR extends its congratulations and best wishes to Dunn and his family.
