St Mirren defeated Partick Thistle 2-1 to reach the Scottish Cup semi-finals, with goals from Dan Nlundulu and Jake Young securing the victory. The win marks St Mirren's third Hampden appearance this season, following their League Cup triumph. Their cup form contrasts sharply with their 10th-place Premiership struggles, highlighting their strength in knockout competitions.

Thistle briefly threatened after Ben Stanway's second-half volley reduced the deficit, but St Mirren held firm. The match featured a controversial VAR decision that awarded Nlundulu a penalty after referee David Dickinson ruled Robbie Crawford had handled the ball. Young then doubled the lead in stoppage time with a clinical finish from Nlundulu's assist.

St Mirren will now face Celtic in a semi-final rematch of the League Cup final, which the Buddies won 3-1. The April 18-19 Hampden clash offers Celtic a chance to avenge that defeat. Meanwhile, Dunfermline and Falkirk were drawn together in the other semi-final, setting up a local derby in the Scottish Gas Scottish Cup last four.
