I don't know if someone posted this already, but here it is...
I'm listening to the banter on the Toronto TV feed about how this is Bay's first as a big leager playing a game in Canada. According to baseball-reference.com, it isn't. It seems as though it is at least his 4th.
July 9, 10, & 11, 2004 - They show him as playing in games two, three, and four of a series when the Pirates visited the Expos.
Here's the link for the first of those games: http://www.baseball-reference.com/boxes/MON/MON200407090.shtml
He went 4 for 5 with 4 runs scored and a home run.
I also saw an article somewhere on BostonHerald.com about tonight being his first. Am I missing something? Is is possible that no one looked this up?
