Napoli has vascular necrosis of the hip joint

Mike Napoli was officially introduced on a conference call with the Red Sox media moments ago. He agreed to a one-year deal for $5 million with an incentive package of $8 million more if he stays healthy based on plate appearances.

Ben Cherington and Napoli’s agent Brian Grieper were also in on the conference call.

Napoli has vascular necrosis of the hip joint, which usually leads to a hip replacement. Napoli said that he didn’t know of the condition and never had symptoms. He said the first he heard of it was when the Red Sox conducted their physical exam.


Napoli and his agent said the condition was found in its early stages and is treated with medication.

Cherington indicated that Napoli should be ready for spring training and he will play primarily first base.

Former baseball and football star Bo Jackson’s career ended with a severe case of the same hip condition.
