What we learned Thursday was Eduardo Rodriguez was being shut down due to "minor" health complications stemming from his recent bout with COVID-19. It was also relayed that the pitcher wouldn't be active for another week, at which point he would be reevaluated.
Now we have an idea of what the issue is.
According to a source, Rodriguez is dealing with a condition involving his heart.
There seems to be a strong possibility the specific affliction is called "myocarditis" which involves the inflammation of the heart muscle. Myocarditis is a situation that is often brought on by a viral infection and can affect your heart muscle and your heart's electrical system, reducing your heart's ability to pump and causing rapid or abnormal heart rhythms.
It explains the need for rest with victims of the disease not able to engage in any sort of activity that would accelerate the heart's functions.
Treatment includes medication and rest, allowing the inflammation around the heart to subside.
There have been numerous reports of COVID-19 patients being diagnosed with myocarditis.
