Red Sox relief pitcher Phillips Valdez tested positive for COVID-19, the 12th player to do so since Kiké Hérnandez first tested positive on Aug. 27.
Pitcher Chris Sale and utility player Danny Santana tested positive earlier this weekend.
Valdez has a 5.85 ERA in 40 innings of work this season, his second in Boston. To fill Valdez’s roster spot, the Sox recalled righty Brad Peacock from Triple-A Worcester.
The Red Sox have 10 players on the COVID-related injured list.
