The Marlins on Monday placed right-hander Elieser Hernandez on the 10-day injured list with right biceps inflammation. Hernandez, who exited his season debut after 34 pitches on Saturday, was scheduled to see a doctor before deciding the next course of action.
First baseman/outfielder Garrett Cooper also landed on the IL with a reaction to the second dose of the COVID-19 vaccine. That stint can be as many days as he needs to recover, with no minimum requirement.
As corresponding roster moves, Miami recalled right-handers Nick Neidert (the club’s No. 12 prospect, per MLB Pipeline) and Jordan Holloway (No. 24). Neidert, who lost out on the fifth-starter spot in 2020, went on to make four multi-inning relief appearances as a rookie last season. This spring, he kept his pitch count up despite once again entering games out of the bullpen. Both Neidert and Holloway were on last season's extended Opening Day roster, and later in the season were both put on the COVID injured list.
