Mike Dunn - Mike Dunn had shoulder surgery in September, which is going to be an offseason mission to get him back on track for the beginning of the 2019 season. Dunn is a lefty reliever, and one of the few Colorado has. There is an option where they look to replace Dunn to a younger reliever with him being 33.
Playing in Colorado can be a tough place to play with the altitude, and we have seen players struggle with staying healthy while playing for the Rockies. We have seen some major talent come through Colorado over the years, and guys like Troy Tulowitzki and Matt Holliday had their share of injuries. But going back even further, we saw Todd Helton start to struggle with more injuries later in his career. Helton went to the 60-day DL back in 2008, where he was having back issues. A few seasons later, Jorge De La Rosa suffered a torn UCL in his pitching elbow, which caused him to miss the rest of the 2011 season.
The Rockies have had one of the better outfield crews over the last decade, but Charlie Blackmon went down in 2011 with a fractured left foot. Carlos Gonzalez was also battling wrist injuries at the time. Things started to look bleak in 2012, as Blackmon began to battle turf toe in his right foot, and De La Rosa had to have Tommy John within the first week of the season. Helton was still with the team, but hip injuries limited his playing time. He eventually had surgery to repair a labrum in his hip. Within the same season, Michael Cuddyer went to the DL several times with a strained right oblique.
Tulowitzki went down with various injuries in his career, fracturing his wrist, ribs, and other ailments over the years. The hip problems later on in his career eventually led to him not finishing out his career. Cuddyer was the same way, as he went to the DL with shoulder problems early in 2014, and never returned. Both would have surgeries, and their time ran out very quick in Colorado as they moved on with younger talent.
Of late, Adam Ottavino was one of the bigger injuries, undergoing Tommy John surgery in 2015. He would be able to return, but has some iffy fatigue trips to the DL that are somewhat of a concern. Justin Morneau could never quite get right from his concussions, and he eventually retired to play it safe. David Dahl is an up and coming young talent but has battled numerous injuries to start his young career.
