After Rob Crutchley and Jon Rees had given Hounslow a 2-0 lead, goals either side of the interval from Richard Gibson put Grinstead on terms, with Ben Barnes getting the winner from the penalty spot in the 54th minute. A goal from Stourport's Mark Harradine and two from David Knott in a five-minute spell in the first half saw off Southgate.
Two goals from Calum Giles, one from Stuart Avery and another from Derek Cunliffe gave Havant, who left the England international Rob Hill on the bench at the start of the game, a 4-1 win against Cannock to stay in third place.
In a game best forgotten Reading beat Indian Gymkhana 2-0. However, Paddy Osborn and three Gymkhana players were given temporary suspensions and Gymkhana's Davinder Rehncy was shown the red card for ungentlemanly conduct.
Ian Jennings, who scored 11 goals for MIM Indoors in Scotland on Saturday, flew south yesterday morning to score four times in Guildford's 6-3 win against Cheltenham which keeps them in second place behind Surbiton at the top of the Second Division.
