...better strategy against The Yankees.
You are jumping to the conclusion that The Yankees have a strategy. Over numerous decadez, it tends to seem to not be the case.
After that incident a few years ago where my beloved team was in the spot of being up 3 games to O, in a best of 7 series for the AL pennant against The Red Sox, and then lost 4 in a row, I don't rule out any team or know what to expect. (and let's not forget that odd year where The Padres managed to get to the WS). Baseball, like all sports is unpredictable.
May the remaining games, whichever teams, be exciting and interesting.
