4 game sweep of Milwaukee was probably just a shade better, since it was for the division. But it's close, and if someone wants to say this is better because it's the first big move by this particular group and it's been so long, I have no argument. I can't even remember the year, but there was a big 5 game set in wrigley against the Cardinals where the Cubs took 4 of 5 that I remember as amazing. I think this included an inning with 10 consecutive hits by the Cubs, though I may be mixing memories. I have googled myself silly trying to find these games. Can anyone help? Edit: the five game series was over Labor Day weekend 2003.
