1. The Red Sox offer him arbitration and
2. Lopez signs a major league deal with another team,
then the Red Sox will snag a sandwich round pick, between the first and second rounds, in the draft. This year Anthony Ranaudo, a preseason top 10 prospect, fell to them in that spot, so the payoff for dropping a few thousand on Lopez could be huge. Of course, considering he's been run out of town by several different teams, the hard part could be getting another team to sign him to a major league deal.
