Major League Baseball Commissioner Rob Manfred said he has “every confidence” there won’t be another can-throwing episode during a game in Toronto during this post-season.

Manfred said Saturday that the sport and the Blue Jays have been working together to prevent the sort of thing that happened during the AL wild-card game, when a spectator chucked a beer can near Baltimore Orioles outfielder Hyun Soo Kim during the seventh inning.

Toronto has been “extremely co-operative and I think is as committed as we are to make sure that we don’t have another incident like that,” he said. The Blue Jays have said they are planning tougher security measures and alcohol policies at their stadium.

The Blue Jays host the Texas Rangers on Sunday in Game 3 of their AL Division Series.

During last year’s ALDS between Texas and Toronto, Blue Jays fans tossed bottles and debris on the field during Game 5, upset by an umpire’s call.

While meeting with reporters, Manfred also addressed several other issues, including bat flips and other celebrations during games.

“Players being more demonstrative on the field is a good thing for the game. I think it’s exciting.” Manfred added: “I have great faith in our players. That they will use good judgment. That they will develop a set of rules that are respectful of the game, but also are reflective of the differences between these young players and the people that may be played a generation ago. I think we should all embrace that.”
