The Blue Jays say they are planning tougher security measures and alcohol policies at the Rogers Centre after a fan threw a can at Baltimore outfielder Hyun Soo Kim during the seventh inning of the AL wild card game.
Toronto apologized Wednesday to the Orioles and pledged to help authorities identify the spectator.
After winning 5-2 in 11 innings Tuesday night, the Blue Jays issued a statement saying they felt "extreme disappointment" that tarnished "an otherwise memorable night."
The team says it will "enact heightened security measures and alcohol policies that will ensure the fan experience and safety of everybody involved."
Toronto Mayor John Tory, speaking on CFRB radio, called the fan a "loon-ball."
