Monaco extended the distance between second and third in the Ligue 1 table with a 1-0 win over Nice on Saturday.
Substitute Tiemoue Bakayoko scored the only goal of the game for Monaco which widens the gap between his second-placed side and next best Nice to six points, as the race for direct qualification for next season's Champions League group stages heats up.
Lyon took full advantage of Nice's slip-up and moved within three points of third place with a thumping 3-0 away win against fourth-placed Angers.
Goalkeeper Jean-Louis Leca was the first to go when he earned a straight red after 48 minutes - Bastia's fifth red card in their last five league games - with his side already 1-0 up courtesy of 10th minute Floyd Ayite strike.
Troyes' Brayan Vargas joined Leca in the stands after 59 minutes with a straight red of his own, before Fabien Camus got one of his own after 82 minutes, with Ayite doubling his tally from the penalty spot to seal the win for the home side.
Goalless draws between Toulouse and Nantes as well as Gazelec Ajaccio and Guingamp rounded out Saturday's action.
