The Red Sox have fumigated and disinfected their clubhouse at Fenway Park to help fight the flu. Boston manager John Farrell says it has been done a few times while the team has been on the road. The Red Sox have been hit hard by the bug. Hanley Ramirez has played just two games because of it, and Mookie Betts returned to the lineup Sunday after the flu kept him out for almost a week.
