CHICAGO (AP) — Chicago White Sox prized pitching prospect Michael Kopech has chosen not to play this season. The team also put star third baseman Yoán Moncada and pitcher Jose Ruiz on the 10-day injured list because of unspecified ailments. The White Sox believe they are poised for a turnaround after seven straight losing seasons. But losing Kopech for the season and Moncada for at least a little while are big blows. Both players had been absent since the White Sox resumed workouts last week for the first time since Major League Baseball shut down camps in March. The team had said Kopech was dealing with a personal issue.
