FORT MYERS, Fla. - Minnesota Twins slugging prospect Miguel Sano will have Tommy John surgery on his throwing arm and miss the 2014 season.
The 20-year-old third baseman had been trying to rehabilitate a strained ulnar collateral ligament in elbow. He was hurt in October while playing winter ball in the Dominican Republic.
Twins doctors, along with orthopedic surgeon Dr. James Andrews, recommended rest for Sano in early November.
Despite making strides during a two-month throwing program, Sano reported pain in his elbow after making an off-balance throw during an intra-squad game Thursday.
An MRI exam revealed a partially torn ligament, and the Twins opted for surgery.
The Twins said the surgery will take place in March. They expect Sano to resume hitting in about four months, and playing the field in eight months.
