Trying to hang on to their slim lead in the American League Central, the Cleveland Guardians lost two starting pitchers to injury on Friday. Both Zach Plesac (broken hand) and Aaron Civale (forearm inflammation) were placed on the 15-day injured list before Cleveland, which leads Minnesota by just one game, opened a three-game series against the Seattle Mariners. It's hardly ideal for a young team in the middle of a pennant race. Plesac was supposed to start Friday's opener, but the right-hander was scratched about four hours before the scheduled first pitch. Rookie Cody Morris will make his major league debut against the Mariners.
