I asked a similar question a while ago [here][1].

I had great success with the [PlayerRatings][2] R package which implements the ELO method popularized by competitive chess along with some slightly more advanced methods such as Glicko and the package authors own method.

By comparing the rankings you can obtain the probability of a team beating another.
