Reece Evans scored twice for Queen's Park
Lowland League leaders East Kilbride threatened a shock win over Scottish Championship hosts Queen's Park before succumbing to an extra-time blitz in their SPFL Trust Trophy semi-final.
The visitors came from two goals behind to draw level at half time, but four goals in the last half hour secured the Glasgow side a place in the final against either Dunfermline Athletic or Livingston.
It took the side sitting fifth in the second tier only a minute to take the lead as striker Zak Rudden fired the opener, with on-loan Aberdeen midfielder Ryan Duncan finding the top corner after 22 minutes.
East Kilbride, who had already knocked out Championship sides Airdrieonians and Ayr United, fired back as midfielder Jack Leitch found the bottom corner 10 minutes later and defender David Ferguson's close-range header levelled just before the break.
However, Reece Evans slotted the Spiders back into the lead a minute into extra time before an own goal from on-loan Motherwell goalkeeper Matty Connelly was followed within seconds by Rudden's second - and fourth in four games - to all but settle the game.
Fellow forward Evans fired his own second in the second half of added time to complete the scoring and end the fifth-tier sides six-game winning run.
Queen's Park will find out their opponents in the final when their two Championship rivals meet at East End Park on 5 February.
