Northampton's stuttering season reached a desperate new low on Saturday when they were hammered 6-0 at home in a remarkable game against Bristol Rovers.Billy Bodin scored against his former club to give Rovers a deserved lead at half-time before the visitors ran riot in the second-half.Ellis Harrison's double, Rory Gaffney's close-range finish and late goals from Liam Sercombe and Dominic Telford wrapped up only a second away league win of the season for Rovers, who climb to 12th as a result.Northampton, who also had Alex Revell sent off on a disastrous afternoon, have now gone five successive league games without scoring and remain in the bottom four.Matt Ingram was by far the busier of the two goalkeepers in a first-half that Rovers dominated as he made three saves before Bodin latched onto Gaffney's lay-off and fired into the bottom corner.Tom Nichols missed the chance to add a second when Ingram saved his spot-kick but that mattered not given what unfolded in a remarkable second half.Harrison headed in Sercombe's fine cross on 56 minutes before sweeping home a second four minutes later.Revell then saw red when clashing with Tom Broadbent and Rovers were in no mood to relent, Gaffney powering in a fourth after Chris Lines' shot hit the post before Nichols' cross was finished off first-time by Sercombe.Marc Bola teed up Telford for a sixth four minutes from time and that was the end of the scoring, much to the home side's relief.
