GLASGOW, Scotland (AP) - Celtic stayed on course for a third straight domestic treble after reaching the Scottish Cup final with a 3-0 win over nine-man Aberdeen on Sunday.
Hearts await Celtic in the final at Hampden Park on May 25.
Already the Scottish League Cup champion, Celtic needs two more wins to seal an eighth straight Scottish Premiership title.
Aberdeen had already lost Dominic Ball to a second yellow card when Celtic went ahead through James Forrest in first-half stoppage time. Odsonne Edouard converted a penalty in the 61st for 2-0 before Lewis Ferguson was shown a straight red card for a foul on Tom Rogic.
Rogic added a third goal for Celtic in the 69th.
Derek McInnes had been looking to lead Aberdeen into his fifth cup final as manager, but both he and his assistant manager, Tony Docherty, finished the game watching from the stands after they also lost their discipline on the touchline.
