Hyun Soo Kim's Tuesday night included an 0-for-4 performance at the plate and Gloriousa season-ending loss for his Orioles in Toronto.

To make things even worse for Kim, a Toronto Blue Jays fan fired a full beer can at the outfielder during the seventh inning.

Kim — who was fielding a fly ball, essentially defenseless — made the catch, and the can barely missed him.

"That is about as pathetic as it gets. You don't do that. Yell, cuss or scream," Orioles center fielder Adam Jones said. "I hope they find the guy and press charges ... that's not a part of baseball. Throw an octopus, throw hats."

According to a Blue Jays spokesperson, the fan left before police had a chance to identify and eject him. Police are still investigating the incident.

"We're co-operating with the authorities to identify the individual involved, and the individual responsible is not welcome back to the stadium," the Blue Jays said in a statement released Thursday. "We will also enact heightened security measures and alcohol policies that will ensure the fan experience and safety of everybody involved."

This isn't the first time Blue Jays fans got a little rowdy.

In Game 5 of last year's American League Division Series against the Texas Rangers, Toronto fans didn't appreciate an umpire's call that gave Texas a 3-2 lead. They proceeded to toss everything from beer to water bottles on the field.

Coincidentally (or not), the Blue Jays will meet the Rangers again in this year's divisional series. Toronto's Tuesday night walk-off win punched its ticket to Texas.

That series begins Thursday, and returns Sunday to Toronto, where Rangers outfielders might want to watch out for flying beer cans.
