Sang Ho Baek—a pitcher at George Mason University—died suddenly after complications from Tommy John surgery on June 12, according to the university's athletic department. He was 20 years old.
Tommy John surgery is a relatively common procedure for pitchers to have on their elbow to reconstruct their ulnar collateral ligament. Baek had recently finished his freshman season at George Mason, appearing in seven games. He debuted against UMBC on March 12.
"Sang was an incredible teammate who was loved by everyone associated with Mason baseball. He will be missed and forever cherished in our hearts," George Mason baseball coach Bill Brown said in a statement.
