Bradford produced a super-charged second-half performance to maintain their unbeaten start to the season with a 3-1 win over previously undefeated Crawley.Bradford's on-loan keeper Jordan Pickford made an important save early on when diving to prevent an own-goal from Gary Liddle following a free-kick by Jimmy Smith.City threatened when Filipe Morais fed fellow midfielder Billy Knott and his goal-bound volley was blocked.Crawley midfielder Bobson Bawling, on his full league debut, should have hit the target when firing over after breaking into the area.Bradford striker Aaron McLean had a shot blocked from a header by James Hanson before Crawley defender Joe Walsh forced Pickford to save smartly with a shot on the turn.Crawley conceded their first goal in four games five minutes after the break when skipper Stephen Darby crossed from the right and Hanson thumped the ball into the roof of the net from 12 yards.The Red Devils hit back to equalise only five minutes later through Walsh who powerfully headed in a corner from Ryan Dickson.Knott struck his first goal for City to restore their advantage on 63 minutes with a volley from 15 yards which went in off the left-hand post.Jason Kennedy struck the bar for City before substitute Mason Bennett sealed the win 13 minutes from time by clipping the ball over Brian Jensen for his first goal for the club from Hanson's flick.
