MLB shortstop Didi Gregoirus, who led the Philadelphia Phillies in runs batted in last season and is used to turning double plays on the field, is looking to help turn around a COVID-19 treatment off the field. Gregorius is partnering with Johns Hopkins University to get the word out about volunteering for a national clinical trial evaluating the use of antibody rich-convalescent plasma therapy as a way to combat COVID-19. Gregorius joined Closing Bell to discuss his partnership with Johns Hopkins, as well as how safe he felt playing during the 2020 season because his teammates were also taking care of themselves.
