I've read (somewhere) the first recognizable baseball game played in North America was in Ontario in 1839.
So, WI pro baseball started around 1840 in Ontario? How much would baseball change?
I'm going to presume it still takes off in the U.S. Enough for the NL & AL to absorb competing leagues, like the Federal or PCL, rather than try & wipe them out?
Would it (perforce) be organized the same way? Is there a maximum number of teams that's possible? Might it not survive the "monopoly challenge" of the Federal League?
Does invention in Canada improve the odds for integration early?
Any other thoughts?
