MILAN (AP) -- AC Milan is through to the Italian Cup quarterfinals after winning 2-0 at 10-man Sampdoria, Rossoneri coach Sinisa Mihajlovic's former team.
M'Baye Niang broke the deadlock five minutes after the break, beating the offside trap to run onto Carlos Bacca's through-ball and fire into the bottom left corner.
Bacca sealed the result in stoppage time, after Samp had missed clearcut chances to level.
Sampdoria's hopes of a comeback started to fade when defender Ervin Zukanovic was dismissed in the 64th minute for picking up two yellow cards in a matter of seconds -- having said something to the referee, moments after being booked for a foul.
Earlier, Lazio came from behind to beat 10-man Udinese 2-1 to book a quarterfinal tie against Juventus, in a rematch of last season's final.
