Johan Santana (shoulder) is scheduled to undergo surgery Tuesday. Santana is dealing with a "probable re-tear" of the anterior capsule in his left shoulder and has decided to undergo a second surgery in an attempt to continue his career. The operation will knock him out for all of this year, and the 34-year-old is far from a guarantee to return next season. The Mets hold a $5.5 million buyout in 2014.
