Every time it looks like the 1-1 is going to slip away, we have a bad series that allows us to rebuild our lead.
Anyway, as of this morning, here is where the race to the bottom stands, including the records in the last 30 games.
Phillies       54-89  --  (12-18)
Giants        56-89  1  (11-19)
White Sox  57-86  3  (12-18)
Tigers         60-83  6  (8-22)
Reds          62-82  7.5 (15-15)
No one else is reasonably in the running, in my opinion, so I exclude them.
