Stade Toulousain scored an eighth victory in a row in all competitions. Toulouse, 2nd at kick-off, and Castres, 3rd, largely turned to the advantage of the Rouge et Noir.
They scored five tries by Juan Cruz Mallia (4th, 49th), Emmanuel Meafou (20th), Joshua Brennan (39th) and Mathis Castro-Pereira (58th) This improved success allows Ugo Mola's men to count 55 points and therefore temporarily steal the lead.
