Which teams have never finished above .500 in a decade? In this case, a decade is 19#0-19#9, and there have been at least a couple teams to do this. Do you know which ones?

Hint: Tampa Bay is not one of them, because of the decade "rule."

The Phillies and Red Sox in the 1920s are a couple of them.

I'm gonna say the Seattle Mariners in the 1980's.
