Toronto Blue Jays
The Blue Jays won back-to-back World Series in 1992 and 1993 and they remain the only team based outside the United States to ever lift the trophy. These Toronto Blue Jays rivalry shirts are built on that legacy. For Canada's only baseball team and the fanbase that fills the building whenever it matters.
The Yankees take the top spot because the AL East rivalry with New York has defined Blue Jays baseball for over forty years, available with text or box designs, censored or fully explicit, in Blue Jays royal blue and white. Anti-Red Sox shirts cover the other Boston-versus-Toronto chapter that's always good for a few games of bad blood, with anti-Orioles and anti-Rays designs rounding out the AL East.
Toronto Blue Jays fan gear for Canada's only baseball fans. Wear it to the Rogers Centre under the CN Tower, to bars across downtown and in Liberty Village, to watch parties anywhere Canadians gather to watch baseball, which is most of the country in October.
Two World Series titles back-to-back. Joe Carter's walk-off home run in Game 6 of 1993, one of the three or four most famous swings in baseball history. Roberto Alomar's glove. Roy Halladay's complete games. The only trophy in MLB that ever left the country. Bautista's bat flip. Go Jays.
