LYNN-For a student who says she wants to become a writer when she grows up, winning a prestigious statewide writing contest in just the fourth grade is not a bad way to start.Sisson Elementary School fourth grader Kerrin Hogan will be honored at the TD Banknorth Garden in Boston next month as the fourth-grade winner of the fourth annual Will McDonough writing contest, celebrating the “Greatest Year in Boston Sports.”The contest, named in honor of the late Boston Globe sports columnist, is designed to encourage the development of language and writing skills while incorporating important elements such as teamwork, courage, determination, resp-onsibility and fairness. Students submitted essays in one of a number of topics, and are judged by Boston Globe editors on development, style and organization.For Hogan, the contest was an opportunity to practice her favorite activity, and come up with a creative story to submit to the judges.Her story, “Baseball is my Sport” was about a kid who loved to play baseball, but whose father wanted desperately for him to go fishing. She included topics of determination and courage, as the main character struggled to find a way to tell his father that baseball was his sport, and he did not want to fish.”He had to use courage and determination to tell his dad, who came to watch him at his game (after he told him),” she said. “It just kind of came to me one morning. I thought it would be a good story.”Hogan says she wants to be a writer when she grows up because she enjoys telling stories and “wants to be rich and live in a mansion.”She says she often writes on her own stories, but admits that she is a perfectionist and usually ends up throwing her stories away because she doesn’t like them.Sisson teacher Christina Colella says she had her entire class take part in the contest, and she is proud to see Hogan come out with the best story in the entire state among fourth graders.”I try to have them write for a different purpose than just having me read it,” she said. “I though this contest would be a good way for them to practice.”Hogan is one of two Lynn students to finish well, as Ford School sixth grader Joke Jolaoso won the sixth grade award for his story “The Life of an Amazing Disabled Athlete.”Winners from each grade will appear at an award ceremony at the Sports Museum within the TD Banknorth Garden, and receive a $100 savings bond. Their families and other guests will join members of the Globe staff and the McDonough family for a reception before watching the Boston Celtics take on the Indiana Pacers.
