According to Ken Rosenthal and C. Trent Rosecrans of The Athletic, Mike Moustakas (illness) and Nick Senzel (illness) have filed an appeal asking to be allowed to return.
This is the situation that teammate Nick Castellanos was referring to in his postgame Zoom call with reporters late Tuesday night, when he expressed frustration that both Moustakas and Senzel had passed the necessary COVID-19 tests but weren't going to be allowed back onto the field until at least Thursday. Cincinnati has gone 0-3 since the two players self-reported symptoms on Sunday morning. Rosenthal and Rosecrans write that Moustakas and Senzel have been deemed "ineligible to play as MLB grapples with the fallout of a reported outbreak among the Marlins." Their case will be heard by a joint committee panel of league and union representatives on Wednesday morning.
