A reserve team is usually made of apprentice and/or newly recruited Quidditch players who are either not yet ready for the first team or are waiting for a place to come free on the senior team (usually due to injury or transfer). Alicia Spinnet had been a reserve Chaser for the Gryffindor team (appointed by Oliver Wood) the year before Harry Potter started at Hogwarts (PS11).
