A second half goal by Roko Prsa gave Hamrun a 1-0 win over Hibernians and moved them eleven points clear at the top of the BOV Premiership.
In a match of few chances, the only goal came just after the hour when Prsa controlled the ball in the box and fired past Haber.
The loss leaves Hibs 13 points behind Spartans with a real struggle on their hands to clinch a place in European football competition later this year.
