Riske went in front of an arbitrator in St. Petersburg, Fla., on Aug. 22, when the Indians were at Tropicana Field to play the Tampa Bay Devil Rays in an effort to try and get his four-game suspension and $1,500 fine reduced.
Bob Watson, director of on-field operations, represented Major League Baseball. Robert Lenaghan, assistant general counsel for the players association, accompanied Riske.
"I told my side," said Riske, who said the process took about an hour. "I told them I didn't hit him on purpose. Bob Watson told their side."
Riske, whose fine also was reduced an undisclosed sum, will begin serving his suspension Friday night when the Indians open a three-game series at Minnesota.
Cleveland starter Kevin Millwood already served his five-game suspension for intentionally hitting a batter in the same game, while Mariners right-hander Shigetoshi Hasegawa was fined an undisclosed amount, but not suspended for hitting Grady Sizemore with a pitch that night. Tribe manager Eric Wedge and bench coach Robby Thompson also have already served their one-game suspensions for their part in the incident.
