See-saw, see-saw, oh so fun!

The classic national league see-saw battle, one team takes the lead, then the other team takes over, over and over and maybe A 3rd time.  Well, thats what's going on in Citi Field.  Mets vs. Cards.  It went from 1-o to 1-3 to 3-3 to 4-3 to 4-7. The mets lead it 7-4 in the 7th.
