NEW YORK -- Chicago White Sox pitcher David Riske was suspended three games by the commissioner's office Thursday for intentionally throwing at St. Louis' Chris Duncan this week.
White Sox manager Ozzie Guillen also was suspended, for one game. He and Riske were each fined an undisclosed amount by Bob Watson, vice president of on-field operations for Major League Baseball.
Riske's suspension was scheduled to start with Thursday night's home game against the Cardinals, unless the reliever appeals. Guillen was required to serve his penalty Thursday -- there was no appeal process available for him.
Riske and Guillen were ejected in the seventh inning of Chicago's 20-6 victory Tuesday night after the right-hander hit Duncan with a pitch.
The benches had been warned in the bottom of the sixth after St. Louis pitcher Sidney Ponson plunked two White Sox batters with the bases loaded.
