- "Harry was faster than Higgs — he could see the little round ball, wings fluttering, darting up ahead — he put on an extra spurt of speed —
WHAM! A roar of rage echoed from the Gryffindors below — Marcus Flint had blocked Harry on purpose, and Harry's broom spun off course, Harry holding on for dear life."
Blocking, in Quidditch, refers to a foul that consists of deliberately putting oneself on the way of the opposing team's Seeker, with the intention of obstructing his way towards the Snitch (usually resulting in a crash between the two players). This foul could be committed by all players.
