Division One side Star saw off Division Three leaders March Sarcens 7-1 even though they played three-quarters of the match with just 10 players.
Star led by a single goal when Kyle Townsend was hurt and boss Marvin Bennett was unable to call on any substitutes due to an injury crisis.
But the setback didn't affect his side as Bradlee Page's hat-trick inspired a goal charge.
Page had opened the scoring when Star still had a full compliment of 11 men and Billy Bennett doubled their advantage before the break.
And they really put the pedal to the metal in the second period as Page and Callum Pacey extended the lead before William May and Brandon Kelly got in on the act with 25-yard screamers.
Page completed his treble before Saracens snatched a consolation.
