Girvan’s unbeaten league record of almost 30 games was halted on Saturday in a seven-goal thriller at Hamilton Park.
In the opening 15 minutes, Clydebank keeper Josh Lumsden comfortably gathered early efforts from Tony Murphy and Robert Paterson.
Bankies were in the lead after nearly 20 minutes with Jordan Shelvey rising highest to beat Girvan goalkeeper Scott Johnstone to the ball as his header looped in.
On the half hour mark Bankies doubled their lead. Little rounding Johnstone and slot in his first of the afternoon. And in a sucker punch for Girvan two minutes before the break, Bankies added a third as Kasubandi fired the ball into the top corner from 18 yards out.
With 60 minutes gone Clydebank’s MacKinnon was caught in possession and Girvan broke away, with Calum Gow heading into his own net from the resulting cross.
Five minutes later, the Seasiders did find their way back into the game with a second goal. After Andy Paterson needlessly conceded a corner, defender John Frame headed past Josh Lumsden.
But minutes later Little was on hand to sweep the ball under Johnstone for his second of the afternoon.
On 90 minutes Girvan grabbed a third through Sean Robertson.
