The Boston Red Sox have apologised to Adam Jones after the Baltimore Orioles man said he was racially abused during Monday's game at Fenway Park.
Jones had a bag of peanuts thrown at him from the crowd and claims he was "called the N-word a handful of times".
The centre fielder called for severe punishment to be handed out to anyone found guilty of such behaviour, and on Tuesday the Red Sox condemned the incident and promised to investigate.
"The Red Sox want to publicly apologise to Adam Jones and the entire Orioles organisation for what occurred at Fenway Park Monday night," a statement on behalf of president Sam Kennedy read.
"No player should have an object thrown at him on the playing field, nor be subjected to any kind of racism at Fenway Park.
"The Red Sox have zero tolerance for such inexcusable behaviour, and our entire organisation and our fans are sickened by the conduct of an ignorant few.
"Such conduct should be reported immediately to Red Sox security, and any spectator behaving in this manner forfeits his/her right to remain in the ballpark, and may be subject to further action. Our review of last night's events is ongoing."
