Sanit grew up boxing, but switched to baseball at age 16.[1] He became a closer in the Cuban National Series for the Industriales.[1][2] When Cuban officials became aware of Sanit's desire to play in the United States, they began to hold back his career to prevent him from being showcased, not allowing him to play on the Cuban national baseball team.[1] As a result, Sanit defected in 2006.[1][3]
Sanit arrived in Mexico, then he went to Costa Rica. Later he went to Guatemala where he had a record of 4–0 and 0.00 of ERA.[4] Then he went to Panama before going to the Dominican Republic.[1]
Sanit made his major league debut on May 12, 2011, after the Yankees purchased his contract earlier in the day.[7] As of 2016 he was one of 12 Yankees pitchers since 1919 to make his debut after turning 29 years old, with the most recent being Richard Bleier in 2016.[8]
On June 16, the Yankees released Sanit to clear a 40-man roster spot for Brian Gordon.[9]
