A superb goal from Scottish pair William Marshall and Gavin Byers - plus a first Sheffield Hallam strike for Billy Root - was not enough to prevent the men’s first team going down 5-3 against second-top East Grinstead.
East Grinstead scored from their first foray into the Sheffield box, when David Condon crashed the ball past an unsighted Jamie Cachia.
Hallam were soon back on terms, however, when Liam Ansell drove in from the right, beat the visiting defence and finished with an excellent reverse stick strike.
Sheffield went on to create several more chances, but they were punished for their profligacy when the visitors netted a second to lead 2-1 at the break.
Hallam endured a slow start to the second period, and they found themselves 4-1 down after some lapses of concentration.
“We knew from the players that they had, that they had the capacity to go up a few gears,” coach Vicky Joel said.
“It is frustrating to see, but we have learned from our mistakes and those dips from us are now shorter, even if they do still result in soft goals.
“We have learned that it takes just seconds to create and score goals, and it was really pleasing to see the response from the boys.”
Root cut the deficit with a smashed reverse stick shot at the ‘keeper’s near post, and Hallam set up a tense finish by making it 4-3 thanks to Byers’ strike, from Marshall’s long pass.
Grinstead put the result beyond doubt late on, taking advantage of a lapse in Hallam concentration to add a fifth.
