Feldman was already ruled out for the season after undergoing season-ending arthroscopic surgery on his right knee days earlier, so his move to the 60-day DL is merely a formality. The transaction will open up a spot on the 40-man roster for Tyler Mahle, whose contract was selected from Triple-A Louisville in advance of his scheduled start Sunday against the Pirates.

This is a tough break for Feldman, who has been bothered by knee issues for most of the season. Rather than try to pitch through the recurring knee soreness, Feldman decided to cut his losses and focus on getting healthy for next season. The 34-year-old will finish the season with an unremarkable 4.77 ERA and 1.36 WHIP through 111.1 innings (21 starts). He's a free agent in the offseason.

The right-hander was clearly still feeling the affects of a nagging knee injury that has been plaguing him for much of the 2017 campaign. Feldman was recently activated off the DL on Aug. 12, and made two sub-par starts before heading back prior to Friday's game. There doesn't appear to be a clear cut timetable for Feldman at this point, while he admitted that he's "not really feeling too confident" about the knee injury at this point in time. It seems likely that the club will slide Asher Wojciechowski into the rotation in his place.

The right-hander went on to admit that he's "not really feeling too confident" about the knee. He's been bothered by knee soreness for the entire season, but the discomfort finally got bad enough after the All-Star break to force him to the DL. The injury has been affecting his velocity, and while it bounced back in his first start off the DL last week, Feldman's fastball was sitting in the low-80s Thursday. He may not throw another pitch for the Reds.
