Giants new version of "Dirty Dozen"

With tonight's 10-8 loss to Milwaukee, the Giants have now given up a remarkable 113 runs over their past 12 games, while scoring 73.  (They've actually been able to win 3 of those games, including a shutout).  When is the last time a team has given up that many runs over a 12-game stretch?

(The pre-humidor Rockies gave up at least 113 runs over a 12-game stretch on numerous occasions, but the Cubs allowed the MOST runs over a 12-game stretch in recent history.  Three of those 12 Cub games DID take place at Coors.  The Giants played 3 of their games at Coors during their current streak.)

Now, if you exclude ANY games involving Coors Field, you have to go all the way back to 1977 to find a worse 12-game stretch for runs allowed ....
