Al Hilal overcame Sergej Milinkovic-Savic's red card as Saud Abdulhamid's late goal sealed a 2-1 victory over Al Ittihad in the King's Cup semi-finals.
Without Karim Benzema, Al Ittihad ultimately lacked the firepower to make their numerical advantage count in Tuesday's clash.
Former Lazio midfielder, who joined Al Hilal as part of their spending spree last year, received a straight red card in the 42nd minute.
Al Ittihad's Abderrazzaq Hamed-Allah cancelled out Micheal's opener, but Abdulhamid popped up with the winner in the 81st minute.
Al Hilal are 10-time King's Cup winners, having won their 10th title last season.
The Saudi Pro League leaders, who are still without the injured Neymar, will now face either Al Khaleej or Cristiano Ronaldo's Al Nassr in the final at the end of May.
Data Debrief: Malcom in the middle
Al Hilal might be missing their star Brazilian Neymar, but his compatriot Malcom is delivering when it comes to playmaking.
The former Zenit attacker set up both of Al Hilal's goals, creating three chances in total and registering a pass accuracy of 92.6 per cent, better than any of his team-mates.
