Lyon Richardson: Everything you need to know

The Reds outrighted Richardson to Triple-A Louisville on Wednesday. Richardson is no longer on the 40-man roster but will remain in the organization after passing through waivers unclaimed. The right-hander finished 2025 with a 4.54 ERA, 1.54 WHIP and 30:21 K:BB across 37.2 regular-season innings for Cincinnati.

The Reds designated Richardson for assignment Saturday, Gordon Wittenmyer of The Cincinnati Enquirer reports. Following the Reds' acquisition of Dane Myers (knee) from Miami on Saturday, Richardson will end up as the roster casualty necessary to create space on the 40-man. The 25-year-old reliever finished 2025 with a 4.54 ERA and 1.54 WHIP alongside a 30:21 K:BB across 37.2 regular-season innings. However, his 4.06 FIP indicates that he performed slightly better than what his base stats suggest, and there's a chance another team in need of bullpen depth claims the right-hander off waivers.

The Reds optioned Richardson to Triple-A Louisville on Thursday. Richardson will be sent down to the minors alongside Yosver Zulueta in order to make room on the active roster for Graham Ashcraft (forearm) and Chase Burns (elbow), both of whom returned from the injured list Thursday. Richardson, 25, surrendered three earned runs in one inning during his lone appearance since being promoted Sept. 3 and now carries a 4.54 ERA and 1.54 WHIP through 37.2 MLB frames.
