Fiorentina and Chievo swept through to the Fifth Round of the Coppa Italia after comfortably beating Reggina and Novara.
The Fourth Round continues today and tomorrow in one-off games.
Fiorentina made short work of Serie B opponents Reggina, crushing them 3-0 at the Stadio Franchi.
Khouma Babacar proved to be the star of the night, as he had several opportunities before breaking through to tap in fellow youth team player Carraro's assist.
The goalkeeper fumbled a Viola corner kick to allow Marco Marchionni the second on the stroke of half-time.
Straight after the restart, Alessio Cerci completed the rout from a Marchionni assist, finishing the move with an angled drive. It could've been four, but a goalline clearance denied Seferovic.
Reggina ended the game with 10 men, as Tedesco saw red for a late tackle on Gianluca Comotto.
Fiorentina go on to face Parma in the next stage of the competition.
Chievo are also through after seeing off Serie B leaders Novara 3-0 at the Bentegodi.
Pablo Granoche got both goals in the space of 12 minutes during the first half.
The hitman pounced on a ricochet off the crossbar to open the scoring, then sprung the offside trap to draw out the goalkeeper and beat him with a daisy-cutter.
De Paula finished it off with a late strike, so Chievo will take on Palermo in the Fifth Round.
The Fourth phase will be completed tomorrow evening, when Bari welcome Livorno. The winners of that tie will take on Milan.
The other Fifth Round fixtures are Napoli-Bologna, Inter-Genoa, Roma-Lazio, Juventus-Catania and Sampdoria-Udinese.
