During our last game, our pitcher Andy suddenly grabbed his wrist after throwing a fastball. Coach Becker asked him if he was OK, and Andy said that it hurt. None of us knew what was wrong with him and he was whisked off to the doctor, who ultimately diagnosed a forearm strain and wrist tendinitis. After three weeks of rehabilitation, Andy finally returned. Coach Becker said he was glad Andy was back, and Andy said he was happy and relieved.
