The Tampa Bay Rays made another roster move prior to their matchup Friday with the Toronto Blue Jays, placing reliever Diego Castillo on the COVID-19 injured list due to side effects from his vaccination.
Castillo has appeared in nine games for Tampa Bay so far in 2021, compiling an 0-1 record, a 2.79 ERA and four saves in six opportunities. He last pitched Wednesday, taking the loss against the Kansas City Royals.
To take his spot on the active roster, reliever Chris Mazza, who was optioned on Thursday, was recalled and Louis Head was selected from the alternate training site.
Steve Carney is the founder and publisher of St. Pete Nine. One of the people most associated with baseball coverage in Tampa Bay, he spent 13 seasons covering the Rays for flagship radio station WDAE, first as producer of Rays Radio broadcasts, then as beat reporter beginning in 2011. He likes new analytics and aged bourbon, and is the owner of one of the ugliest knuckleballs ever witnessed by baseball scouts.
