Time for another fun foray into trivia land ... on this Canada Day, one new rule applies -- your question must somehow involve Canada (Expos, Blue Jays, Royals, Olympics, native sons, whatever).
All the other usual rules apply -- no looking up the answer using an internet resource, books are fine, you're the first one to get the answer right, you ask the next question.
And here's the first question (it's a doozy) ...
What Brandon, Manitoba native holds the record for best winning percentage by a native-born Canadian big league pitcher (minimum 100 career decisions)?
