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 Felipe suddenly grabbed his wrist after throwing a fastball. Coach Hoffman asked him if he was OK, and Felipe 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, Felipe finally returned. Coach Hoffman said he was glad Felipe was back, and Felipe said he was happy and relieved.
