Cincinnati Bullpen Shuffle: Johnson Out, Richardson In, Nicolas DFA'd

The Reds are making immediate moves in their bullpen after right-hander Pierce Johnson landed on the injured list with right elbow inflammation. To create a 40-man roster slot for Lyon Richardson's recall from the minor leagues, Cincinnati designated right-hander Kyle Nicolas for assignment. The domino effect is quick: Johnson exits, Richardson arrives, Nicolas leaves.

Johnson's elbow issue is the concerning thread here. He's been a workable arm in Cincinnati's relief mix—not a closer, not a high-leverage specialist, but someone capable of eating mid-to-late-inning innings without imploding. The inflammation suggests either a mechanical creep or overuse, and the timing matters: May injuries to right-arm relievers often signal deeper fatigue in a bullpen that's already been asked to cover more innings than the rotation can hold. The Reds' starters have posted a 4.28 ERA over their past 15 games, well above league average, which means the pen has been in constant triage mode.

Richardson's promotion is the team's counter-move. His minor-league body of work suggests fastball-heavy, strikeout-oriented stuff—useful traits in a 23-year-old arm trying to establish himself. But "useful" and "immediately trusted in high-leverage spots" are not the same thing. The Reds are betting Richardson can absorb some of Johnson's workload, but that's essentially doubling down on a younger, less-proven commodity. Nicolas, the outgoing arm, didn't stick; the DFA signals the organization views Richardson—or someone else on the waiver wire—as a better long-term fit.

For prop bettors, the bullpen instability cuts both ways. On one hand, the loss of Johnson (however marginal his role) and the insertion of an unproven arm increases volatility in leverage situations—games that were coin-flips suddenly have more variance. On the other hand, if Richardson arrives with plus strikeout metrics (something to confirm in preseason splits), the Reds' bullpen strikeout rate could spike in the short term, especially if he's being deployed in earlier innings to build confidence. Watch Cincinnati's bullpen-wide K/9 prop over the next 10 days: if it ticks above 9.5 against its season average of 8.8, Richardson's velocity and stuff are making a measurable dent. That edge survives only the next week or two before the market catches up to the actual usage pattern.

For team-total unders on Reds games in the near term (next 7-10 days), there's modest caution warranted. A bullpen in flux, coupled with Johnson's absence, means a higher likelihood of blown leads and extra innings—situations that suppress final run totals. If Cincinnati was hovering around 4.2-4.5 total runs on the season, a reliable 3.8-4.0 floor is harder to find when the relief corps is reassembling mid-May.
