Stand on Guard 4 Thee

Let's assume Adam Loewen gets into a game this month. If Loewen plays, then the Jays will have had four Canadians on their roster at one time or another this year: Loewen, Brett Lawrie, and Mark Teahen, all of whom are active at the moment, plus Scott Richmond, who got into a single game back in the early season.There has been one other year in which the Jays have had four Canadians on the roster, not necessarily at the same time. Which four?Go!
