Harrow Borough 2 Staines Town 1
Andray Baptiste produced a string of fine saves as Harrow stunned in-form Staines on Tuesday.
Trailing at half time, the hosts upped their game in the second period but were indebted to a brace of outstanding stops by their imposing goal-keeper.
Baptiste, who has only recently returned to action after a two week lay off with an injured knee, came out on top in two one-on-one situations before goals from Dewayne Clarke and substitute Gary Noel sealed victory.
"Andray made two goal-saving saves in the second half," said Borough manager David Howell.
"We had a shaky patch and Andray kept us in it.
"We had not really got going in the first half but were much better in the second."
That owned much to Howell's tacical switch and formation change. He reverted from 4-5-1 to 4-4-2 and threw on young striker Noel, who responded with a late winner after Clarke had equalised from Jonathan Constant's pinpoint cross.
"It was a ball over the top, Gary has got onto it and broke free of their centre back before producing a very clinical finish."
Howell suggested a touch of arrogance on Staines' part aided the visitors' downfall but took nothing away from his side's efforts.
"I think Staines were thinking they were going to win their seventh game in a row here," he added.
"But we put in a good performance which has given all the lads a boost."
