According to Jeff Passan of Yahoo! Sports, the Red Sox have made a multiyear contract offer to first baseman Mike Napoli. The slugger is planning to shop around and explore free agency before making a decision.
Napoli, 32, signed a one-year contract worth $5 million with the Red Sox last winter after a three-year, $39 million pact fell through over concerns about his hips.
The Red Sox made Napoli a qualifying offer earlier this week, which he will surely reject prior to Monday’s deadline. Boston will receive a supplemental first round pick if he signs elsewhere.
