National anthem at Blue Jays games?

When I went to Vancouver BC to see a spring training game Blue Jays against the Mariners they played the Star Spangled Banner and then O Canada. When I was in Seattle watching the two teams they played O Canada and then the Star Spangled Banner. When I was in Vancouver during the Star Spangled Banner I saw a fan do a thumbs down. He was really lucky he wasn't sitting in front of me or he would have found some ice going down his back.

First ... The Blue Jays are a baseball team. You have posted this question in the Canadian Football category. Regardless of the venue of where the game is played, and this applies to all sports, if a Canadian team is involved, both the American and Canadian national anthems are played. If the two teams are from Canada, only O Canada is played. Likewise, if both teams are American based, only the Star Spangled Banner is played. Typically, players do not salute during the anthems. They'll just stand at attention. I dont think there is anything to "deal with" when an American-born player signs to play for a team in Canada. They know (or should expect) that it comes with the territory of having the Canadian anthem played. Getting paid millions of dollars a year, I can't think of one who complained that he had to listen to another country's anthem ... I can't believe I just answered this dumb question... oh well, 2 points for me

When a Canadian team plays in a US stadium or arena, they do play "O Canada" before the US anthem.

Both

Both.

They sing both.

Hurrah, that's what I was looking for! Thanks to author of this question.
