I was just gazing at standings this morning and noticed a deep peculiarity in the "last 10 games" column.  The National League is a whoping 34 games under .500 over the last ten contests.  I knew the AL was winning the inter-league war, but I did not think it was that bad.  The last 10 games numbers really hit home.

Only the Brewers, at 8-2, have a winning record for the last week and a half... with the Mets, Cubs, Rockies and the Birds at 5-5.  On the other side, Kansas City (with some help from us) has a sparkling 9-1 mark... but that aberration  by no means accounts for the disparity.  

My simple question is:  what do you think explains this huge dip between the leagues? {and note, the numbers have been similar in the past few years also.}
