GS: Martin Sutherland 48-F
CARDS: GREEN: David Smith, Will Blyth YELLOW: Ethan Chapman x2 (technical red)
Durham University students were left checking their pockets for wallets and other valuables as Sheffield performed the classic smash and grab.
A solitary solo goal by utility payer, Martin Sutherland, was enough to bag all three points and move the team up the North Conference.
The squad travelled to England Hockey's northern most outpost a man down with three regular players now sidelined through injury.
However, the team were able to give Italian Luca Lixi his first National League cap.
A goalless first half was punctuated by half chance for both teams.
The home side made more and came closest to taking the lead. Sheffield, for their part, only really got close once.
The second half continued in the same vein, with neither side being able to impose themselves on the game.
The tally of double turnovers quickly rose as the game started to lose focus. Durham won a few penalty corners but either misfired or found Simon Hujwan resolute in the visitors' goal.
Hallam regrouped and with thirteen minutes of the second half gone, found Sutherland wide on the left hand side, just outside the 23m line.
He dropped his left shoulder then jinked to the right and made a beeline for the circle.
With three or four home defenders hanging on his tail coat, he drove with pace and power across the top of the circle, neatly sliding the ball past Peter Ellis in the Durham goal.
Wild celebrations were followed by one of the most dogged Hallam performances.
Skipper David Smith had a short sit downside needed first aid to a head wound.
Unfortunately, one rash challenge and one dubious award of a yellow meant Ethan Brown seeing red and having to sit out the last five minutes of the match. Hallam held on, even when faced with two penalty corners after the final whistle to collect their first away win of the season.
Next up, Preston away.
