The Tigers, without Leigh Lanham, and with three guests, were simply no match for a Bandits’ side whose sights are now firmly set on an end of season play-off place.
Simon Stead, after starting with two second places, finished off with four impressive victories, but he scored more than half his side’s points and was their only bright spot in an otherwise disappointing night for the visitors.
Berwick, meanwhile, apart from David Bellego, who was suffering from bike problems, were solid down the line, and the inclusion of Alex Edberg at reserve, alongside the in-form Matej Kus, gave them a potent tail, paid for 20 points between them.
A run of four opening heat advantages, including three 5-1s, saw Bandits open up a 19-5 lead, which meant Stead had to go for double points as early as heat five.
But Matty Wethers, in one of his best meetings of the season, popped out of the start and led the England man all the way to the flag.
The home wins kept on coming and a 5-1 from Edberg and Kevin Doolan in seven took the score to a commanding 31-13, which meant Sheffield had to wait until heat seven before Stead picked up their first race win of the night.
Wethers made a great pass of Justin Sedgmen in heat nine - he did it again in heat 13 - to join Steen Jensen for another 5-1, and with Claus Vissing making it three wins out of three in ten the score moved on to 42-20. Stead got into his stride and went on to win in heats 11, 13 and 15 and on the night he was the only Tiger to beat Wethers, Vissing, Jensen and Kus.
Overall this was a solid and impressive performance from Berwick, but Sheffield were by no means the strongest side to have visited the Borders this season.
