CINCINNATI -- Reds left-hander Brandon Williamson tested positive for COVID-19 and will miss his scheduled start on Sunday, the team said.
He is the fourth Reds pitcher to test positive this week, further jeopardizing the team's postseason chances.
Starter Hunter Greene was placed on the COVID-19 injured list following his 4-1 win at San Francisco on Wednesday. Right-handed relievers Fernando Cruz and Ben Lively were placed on the list between games of Friday's doubleheader against the Cubs.
Manager David Bell said a couple of support staff members have tested positive as well.
