The last day of interleague play features a double header in Philadephia and a great starting pitcher showdown in the subway series as R.A. Dickey and C.C. Sabathia look to assert themselves as the top starting pitcher in New York. There's a slight chance of rain in a few games, but nothing to be concerned about. The league doesn't want to reschedule interleague games later in the season, so they'll do whatever it takes to get the games in if necessary.
