Birrer was the only pitcher since '54 to do it in relief.

Carpenter is just the 5th pitcher since 1954 to drive in 6 more runs than he allowed. No one has done better:

The Phillies have hit a whopping 11 grand slams this year.

There are a couple of ways to find this data but the easiest is to go the the major league batting splits for 2009.

Here's a shared table from there for batting with the bases loaded.

Pretty big discrepancy there, with the Phillies whacking 11 grannies and the Braves and Angels both coming up empty.

For comparison, last year the White Sox hit 12 grand slams. In 2007, four teams tied for the lead with 8. In 2006 the leader was the Indians with 14.
