Dunn was released by the Rockies on Sunday, Kyle Newman of The Denver Post reports. Dunn battled shoulder issues and struggled to a 7.13 ERA and 1.30 WHIP in 17.2 innings with the Rockies before being designated for assignment and ultimately cut loose.
Dunn was designated for assignment Tuesday. Dunn owns a poor 7.13 ERA in 17.2 innings on the season, inflated by the four runs he allowed in just one-third of an inning in his most recent appearance Friday against the Padres. Infielder Pat Valaika was called up to take his place on the roster.
Dunn (shoulder) was placed on the 10-day injured list Thursday, Thomas Harding of MLB.com reports. It's unclear when Dunn suffered the injury, which is being described as shoulder inflammation, or how long it will keep him sidelined at this point. Prior to landing on the shelf, Dunn compiled a lackluster 5.19 ERA, 1.10 WHIP and 14:6 K:BB in 17.1 innings of relief (27 appearances). Thursday's starter, Peter Lambert, was summoned to the majors in a corresponding move.
Dunn (shoulder) is listed among the Rockies' available relievers for Monday's Cactus League game against the Rangers, Patrick Saunders of The Denver Post reports. The Rockies eased Dunn into spring action after he required surgery on his left shoulder in September. The southpaw was cleared to make his Cactus League debut Friday versus the Athletics and aced his first test, striking out one as part of a 1-2-3 inning. If used again Monday, he'll likely be in store for another one-inning appearance.
Manager Bud Black said Friday that he expects Dunn (shoulder) to be ready to go for Opening Day, Thomas Harding of MLB.com reports. "We will monitor him closely early in spring training," Black said. "He's currently throwing off the mound and feeling good." Dunn was shut down in July with inflammation in the AC joint of his left shoulder and ultimately required season-ending surgery in September. While it doesn't sound like any reconstructive work was necessary for Dunn's shoulder, the Rockies will most likely limit his usage in Cactus League play to avoid a setback heading into the regular season. The southpaw reliever hasn't lived up to expectations since inking a three-year, $19 million deal in December 2016, accruing a 5.61 ERA and 69:46 K:BB across 67.1 innings in 93 appearances.
