Red Sox prospect Westmoreland undergoing brain surgery

FORT MYERS, Fla. - Boston Red Sox minor league outfielder Ryan Westmoreland needs brain surgery after he was diagnosed with a cavernous malformation.

The Red Sox announced Saturday night that the 19-year-old Westmoreland, one of the team's top prospects, has taken medical leave from minor league camp to seek treatment.

A cavernous malformation of cavernoma is a cluster of abnormal or dilated blood vessels that effects the central nervous system. Symptoms can include bleeding in the brain, seizures and headaches.

Westmoreland left minor league camp March 4, the team says, and was diagnosed the next day at Massachusetts General Hospital.

He is scheduled to have surgery in Phoenix on Tuesday.
