TR,
Found the thread. The bet on my part was that the Yankees would finish ahead of the Red Sox. The Yankees won the division so I could claim victory on that account. The race ended up tied so you could claim victory on that account. I'll settle for owing each other a cup of coffee if we ever meet.
However, in the same thread Phillyfan said he'd wear a Yankees t-shirt if they didn't win the division by at least 10 games.
Phillyfan,
We'll be waiting for photographic proof.
