Former ATP finalist and Miami Open tournament director James Blake has been fined for breaching betting sponsorship rules, the International Tennis Integrity Agency (ITIA) said on Wednesday, while adding the breach was not intentional.

The American former world number four accepted the $56,250 fine along with a suspended fine of $131,250 and a suspended ban of 18 months and fully co-operated with the investigation, the ITIA said in a statement.
