LUSAIL, Qatar - Ducati's defending world champion Francesco Bagnaia won the MotoGP season-opening Qatar Grand Prix on Sunday after taking the lead on the opening lap to beat Red Bull KTM's Brad Binder and Pramac Racing's pole sitter Jorge Martin.

Bagnaia had finished fourth in Saturday's sprint but his faultless ride to take the chequered flag in the race moved him to the top of the championship with 31 points.
