Kirke became a Beater on the Gryffindor Quidditch team, along with Jack Sloper, in 1995. They took over the positions after Fred and George Weasley were given a life-long ban from Quidditch by Dolores Umbridge (their bans were lifted right after Umbridge was removed from Hogwarts). Angelina Johnson, the team Captain, was unimpressed by Kirke and Sloper's performances during try-outs, but considered them to be better than the others who had tried out. Ron Weasley considered them to be dreadful players, even worse than he was.
During Gryffindor's quick defeat to Hufflepuff, Kirke had a pitiful performance; when Zacharias Smith flew in his direction carrying the Quaffle, Kirke shrieked and fell off his broomstick. Ginny Weasley caught the Golden Snitch twenty-two minutes into the match, causing Gryffindor to lose by only ten points.
