No I meant regular season history so the great WS series and playoff series don't count, nor all the playoff victories.
I agree some of those Sept. series in our title year were probably bigger because the division lead was dwindling away.
Of course the series in KC in 1969 (or was it 67) when the Sox s*** their pants was a huge series, costing the team the pennant.
But in terms of a big regular season series, this has to be right up there with the biggest in history in terms of one complete series, not just a game to clinch the division or something.
