The Red Sox don't typically allow the details of their contract offers to leak, but the offer made to free agent slugger Mark Teixeira is expected to be an eight-year deal worth between $145 and $175 million, or possibly more.

The offer is expected to be a record for the team's current ownership group, regardless. Teixeira reportedly has an eight-year offer worth $160 million from the Nationals, and a seven-year offer worth $150 million from the Orioles.

Boston will likely give Teixeira $18 to $22 million annually, unless agent Scott Boras is able to pry more away from the Sox.
