There are two ways that Mike Napoli can earn an extra $8 million this season.
He must either stay on the active roster for at least 165 days or get 625 plate appearances with at least 120 days on the roster.
Napoli and the Red Sox reached a $39 million, three-year agreement on Dec. 3, subject to a physical. After doctors detected a hip condition, the sides finalized a one-year deal this week guaranteeing $5 million and allowing him to earn $8 million in bonuses.
