Cleveland Guardians place Zach Plesac, Aaron Civale on injured list 4:26 PM ET Associated Press CLEVELAND -- Trying to hang on to their slim lead in the American League Central, the Guardians lost two starting pitchers to injury on Friday.

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. Editor's Picks The Guardians said Plesac has a fractured fifth metacarpal. He has been plagued by a lack of run support this season and is 3-11 with a 4.39 ERA in 23 starts. This will be Civale's third trip to the injured list this season. The right-hander missed time with a wrist sprain and a strained glute. He is 2-6 with a 5.40 ERA in 16 games. The 25-year-old Morris was activated from the 60-day injured list Thursday. The right-hander had been sidelined with a back strain suffered during spring training. At Triple-A Columbus, he posted a 2.35 ERA in six appearances.
