Norris claims impressive Miami Sprint win, Antonelli demoted by penalty

Lando Norris claimed the first win of his world title defence with an impressive victory in the Miami Sprint in a one-two for much-improved McLaren.

Mercedes' title-leading Kimi Antonelli finished fourth on the road but was relegated to sixth immediately after the 19-lap race by a five-second penalty for repeat track limits infringements, with team-mate George Russell promoted a place to fourth, which sees the Briton trim his team-mate's title lead to seven points.
