Toronto's Major League Baseball team (a Toronto icon and a source of pride) plays at the Rogers Centre – it's the only MLB franchise based outside the USA. Buy tickets through Ticketmaster (www.ticketmaster.ca) or at the Rogers Centre box office near Gate 9. Try for seats along the lower (pricier) level baselines: you'll have a better chance of catching a foul ball.
The Jays haven't won the World Series since 1993, but who knows – this could be their year.
