Sutton led 7-5 after two quarters but, perhaps crucially, Wanderers missed a penalty that would have brought them back into contention at the start of the third.
This sparked Sutton's experienced team into a dominant spell, goals by Ashley Castle (2), Ryan Symington and Stephen Bayles stretching the lead to to 11-7, a deficit that Wanderers couldn't seriously challenge in the final period.
Polytechnic cruised to a 19-7 win against Cheltenham - a margin that looked unlikely early in the second period when Cheltenham were competing and trailing only 4-3. A wonderful goal by Caleb Simpson, firing a long shot into the far corner from a difficult angle, brought Poly to life. Their lead was 9-4 after two periods; they dominated the third, adding eight more goals while conceding one.
City of Manchester were too strong for Sheffield Sharks in the women's Super 5s, also at Aldershot, winning 16-7. Otter lost for the second time - 14-11 to Coventry.
In women's Championship 1 at Bolton, Cheltenham beat Rotherham Metro 14-11 to complete a perfect weekend of three wins. India Wilkinson scored seven as Hucknall defeated Exeter 16-5 while Honor Grimes hit nine - and Amelia Crompton six - in Tyldesley's 16-12 defeat of Penguin Emperors.
