Sounds like this will be the case.

Rob Manfred says there will be changes in the alcohol policy in Toronto when the Blue Jays return home this weekend for the Division Series. "We've talked to the Blue Jays," Manfred said Wednesday before the NL Wild Card Game. "I think, most important, we are working very hard to locate the individual involved (who threw the beer can into the outfield). I think from a deterrent perspective, it's important to follow up and make sure that he's prosecuted to the extent available. We've also talked to the Blue Jays about the policies with respect to the serving of alcohol. No cans, those sorts of things, to make sure that we have as positive an environment going forward as possible."
