Braces from debutant Marc Richards and substitute Timi Elsnik inspired Swindon to come from behind to beat 10-man Crewe 4-3 in a spectacular match at the County Ground.Swindon initially went ahead when Ellis Iandolo's low cross fell to Richards in the box and the former Northampton striker cooly fired home from 12 yards.Crewe equalised when the hosts failed to clear their lines and Callum Ainley hit a low volley across goal into the far corner.The visitors then took the lead before half-time when Ainley glanced Charlie Kirk's pinpoint cross into the bottom right corner for his fifth goal of the season.David Artell's men extended their advantage early in the second half when Reice Charles-Cook parried Jordan Bowery's initial shot and Ryan Wintle ran in to tap the ball into the net from close range.Swindon had a lifeline with 25 minutes to go when Elsnik curled a shot into the top left corner from the edge of the box, before the Derby loanee equalised with a composed low shot into the bottom left corner. The visitors were reduced to 10 men after Zoumana Bakayogo received a second yellow card and with just minutes remaining Matt Taylor's low cross was poked home by Richards at the front post to win it for the home side.
