Thursday marked the 165th day that Mike Napoli was on the Red Sox' active roster. It wasn't just any other day for him -- 165 days means he gets the full value of the bonuses put into his contract, which means he earned himself an additional $8 million in salary.
Napoli originally signed a three-year, $39 million deal with Boston, but it was reworked when it was revealed that he had a degenerative hip condition. Napoli took the opportunity to sign a one-year deal in order to prove he could withstand a season despite his hip, and was offered staggered bonuses for days on the active roster and for plate appearances, with the ability to reach the full and original $13 million offered to him for 2013 only coming through 165 days on the roster. Napoli has not hit the disabled list at all this year, and while he's had a few days off here and there to rest his plantar fasciitis, it's been a mostly healthy campaign.
The Red Sox first baseman is hitting .258/.351/.478, good for a 123 OPS+, and has produced over three wins according to both Baseball Reference and FanGraphs. He's been a significant part of Boston's success, and is representative of the Red Sox approach to a balanced lineup top-to-bottom, rather than one dominated by stars.
