E-Rod expected in 2021
Though lefty Eduardo Rodriguez continues to be under evaluation for the Myocarditis (inflammation of the heart) that prevented him from pitching this season, the Red Sox have no reason to believe he won’t be healthy come next season.
“We plan on him having a good offseason, building back up, being ready to go next year. Hopefully, that’s still the case,” Red Sox manager Ron Roenicke said. “I haven’t heard anything otherwise.”
