Lazio ended Bologna's Italian Cup title defence on Wednesday, winning 4–1 on penalties after their quarterfinal finished level at 1–1.
Bologna led through Santiago Castro's first-half goal but Lazio replied with a goal from Tijjani Noslin early in the second period.
Lazio converted all four of their attempts in the shootout as Bologna captain Lewis Ferguson had his kick saved and Riccardo Orsolini drove his effort wide.
Bologna lifted the cup last season to end a 51-year wait for a major trophy, beating AC Milan in the final.
Lazio go on to play Atalanta in the two-legged semifinals, while Inter Milan face Como.
The first legs are scheduled for early March with the return fixtures due to take place in late April.
