Read the following excerpt from a student essay. How can the writer best improve his or her narrative voice?
During our last game, our pitcher Hansen suddenly grabbed his wrist after throwing a fastball. Coach Chu asked him if he was OK, and Hansen 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, Hansen finally returned. Coach Chu said he was glad Hansen was back, and Hansen said he was happy and relieved.
