A long list of factors go into determining if a team will be a seller at the MLB trade deadline.
Some teams will be so far back in the standings by July 31 that it makes sense for them to make deals, while others face more difficult decisions because of the potential to gain ground in the pennant races.
Since pitching is in high demand at this year's deadline, the teams with the best available hurlers could drive up the asking price, which may lead to deals not getting done with some potential buyers.
There is also the possibility of trading within division, which could be an issue to a few teams, or could be used as a factor to raise the price for specific players.
