Mevlut Erdinc's double sent Rennes through to the last 16 of the Coupe de la Ligue with a 3-2 win over fellow Ligue 1 strugglers Nancy.
Erdinc's 27th and 47 minute strikes put Rennes in command of the tie after Romain Alessandrini had cancelled out Djamel Bakar's early opener for Nancy. Benjamin Moukandjo scored a late consolation for the visitors.
Ligue 1 Bastia shrugged off four straight losses to ease past third-tier Metz 3-0. Toifilou Maoulida scored twice for the hosts while the visitors had Ali Bamba sent off after 18 minutes.
Auxerre, who have made a poor start to life in Ligue 2 following relegation last season, also reached the last 16 with a 2-0 win over fellow Ligue 2 side Angers.
Despite the 16th minute sending-off of Cameroon midfielder Georges Mandjeck, Auxerre took the lead two minutes later through Paul Ntep and Terence Makengo added a second from the spot moments later.
