The Red Sox have made a five-year offer to free agent slugger J.D. Martinez, USA TODAY's Bob Nightengale reported.

Nightengale didn't report how much money Boston offered.

President of baseball operations Dave Dombrowski has said his priority is to add a middle of the order hitter. But he has had a quiet offseason so far. His only move of any real significance: re-signing first baseman Mitch Moreland to a two-year deal.
