Derek McInnes celebrated his first win as Rangers manager with an impressive 5-1 victory over St Mirren, advancing the club to the quarter-finals of the Scottish League Cup where they will face rivals Celtic.

The scoring opened with Ryan Naderi netting his first goal since April, followed by a stunning long-range volley from summer signing Vanja Dragojevic. Although Chris Mochrie provided a brief response with a spectacular strike for St Mirren, the visitors struggled in the second half.

Key highlights from the match include:

• Djeidi Gassama scoring the third goal, assisted by new signing James Penrice.
• Penrice marking his debut with a goal in the 54th minute.
• Substitute Ross McCausland scoring on his return after 16 months.

In other matches, Heart of Midlothian and Hibernian also progressed smoothly. Notably, Stenhousemuir pulled off a stunning upset, eliminating last year's semi-finalists Motherwell with a dramatic extra-time goal from Euan O'Reilly. This win marked a seventh consecutive victory for Marvin Bartley as the Warriors' boss.

At Tynecastle, Heart of Midlothian overcame a scare against Inverness Caledonian Thistle, scoring four late goals to secure a 6-2 victory. Goals came from Christian Borchgrevink, Rogers Mato, James Wilson, and Claudio Braga, with Calvin Miller netting a brace.

David Gray’s side managed a narrow win against Partick Thistle, thanks to a first-half strike from Owen Elding.
