Carrasco was fighting a fever throughout his Wednesday start against the White Sox, MLB.com's Jordan Bastian reports.
Terry Francona made sense of why he pulled his starting pitcher after just six innings and 91 pitches -- both of which were Carrasco's lowest totals since his first outing of the season. Onlookers would have no idea the 30-year-old was battling an illness based on the performance that earned him a victory. In six starts this year, Carrasco has turned in a 2.18 ERA, which currently ranks ninth among AL starters. He's also tied with Dodgers ace Clayton Kershaw for the third-most innings (41.1) in MLB.
