Pitcher Brandon Workman’s six-game suspension was upheld by Major League Baseball, the Red Sox confirmed Wednesday.
Workman’s suspension, which was orginally issued June 3 and began Wednesday against the Minnesota Twins, was handed down after he threw a pitch behind the head of the Tampa Bay Rays’ Evan Longoria on May 30.
The MLB heard Workman’s appeal Friday, before ruling to sideline the righthander, who has started five games this season with a 2.88 ERA. Workman was slated to start Friday against Oakland.
The Red Sox also released outfielder Grady Sizemore Wednesday, a day after designating him for assignment.
