Jesse Winker - Jesse Winker went down late in the 2018 season, undergoing surgery on his right shoulder. Winker is hoping that he will be ready for Opening Day, but it is not a guarantee either. Winker was having a strong season, and a bright spot for the Reds. He hit .299 with a .405 OBP. He is slated to be the starting right fielder and will be looking to regain a high spot in the order if he is healthy.
Lucas Sims - When the Reds traded Adam Duvall, they got a prospect starter in Lucas Sims for a return. Sims has a way to go to crack the rotation, and will likely be a long relief guy. Outside of Raisel Iglesias, there is not a lock for the rotation, nor is there a long term solution. With a few guys on a short leash, Sims might have a chance to get some spot starts and a rotation spot. He was dealing with an arm issue towards the end of last season, and will rehab over the offseason.
It was unfortunate, but when Ken Griffey Jr moved to Cincinnati, we started to see the injuries for him pile up a bit and limit him towards the end of his career. Griffey missed a good portion of the 2004 season with a hamstring tear. It was the same thing for Barry Larkin, who was in Cincinnati for most of his career. Eddie Guardado was a pitcher for the Reds back in 2007, and was one of the many to go down with ligament replacement. He needed Tommy John, and missed the entire 2007 season. Norris Hopper was in the same boat a few years later, repairing a torn UCL in his pitching arm.
Before Edwin Encarnacion made a name for himself in Toronto and Cleveland, he played for Cincinnati. He went down in 2009 with a fractured wrist. It was a few weeks later that Jay Bruce did the same. It was later in the 2009 season that Edinson Volquez had right elbow tendinitis and was out for the season to undergo surgery. Volquez would make a full recovery and go onto play for some other teams. It was a tough year for Johnny Cueto in 2013, where he was dealing with shoulder issues, and eventually just sat out the second half of the season to recover.
2015 was a rough year for the Reds as they saw Zack Cozart and Devin Mesoraco both going down with surgery. Billy Hamilton and Raisel Iglesias both saw multiple trips to the DL. While Homer Bailey has struggled in the bigs, his 2016 went down with a trip to the DL with Tommy John surgery. The Reds have been plagued by injuries, and eventually the battered bodies get moved onto other teams. The Reds shipped out Mesoraco after multiple lengthy DL stints.
