The Reds signed Fletcher to a minor-league contract Thursday.
Fletcher has been assigned to Triple-A Louisville. The 29-year-old has spent most of the 2026 campaign in the Pirates' organization, where he slashed .301/.386/.485 with eight home runs, 32 RBI, 42 runs scored, three stolen bases and a 26:34 BB:K across 237 plate appearances with Triple-A Indianapolis before being released last month.
