The youngster dummied his way over the line with just minutes to spare after Leeds came back from a six point deficit.Saints had the better of the first half to take the lead but couldn’t create enough chances in the second.They were in front through a Mark Percival penalty in the tenth minute after Kyle Amor was held down in front of the sticks.Kallum Watkins replied with a two pointer of his own before Percival missed the chance to put Saints back in front with another penalty attempt.Both sides struggled to keep hold of the ball on a fine night, but that was interrupted as superb Saints defence stopped a certain Rhinos’ try down the left hand side and then Regan Grace cleared his lines with a class run.And when Tommy Makinson did the same around five minutes from the break, Saints profited.The influential James Roby, who was a cut above all night, broke free and offloaded to Zeb Taia who duly turned it inside for Jonny Lomax to go under the sticks.Up six at the break, Saints were on the front foot from the start of the second, putting a high ball right onto the Leeds’ line that the home side had to defend.But Ryan Hall scored for the Rhinos on 47 minutes after Saints were harshly penalised for obstruction in midfield.Watkins tagging on the conversion to make it all square.Saints weathered more pressure before Watkins missed the chance to put the Rhinos ahead with a chip shot penalty on 58 minutes.The number of defended sets were beginning to tell though and it was no surprise when the home side took the lead – even though it came from a contentious call.A last tackle kick won them a repeat set and when they gained another Adam Cuthbertson charged over from close range.It was fortuitous considering the kick previous had been collected in an offside position – but the finish was anything but lucky.Another fortuitous penalty then saw Watkins extend the Rhinos’ lead to eight – LMS adjudged to have obstructed on a grubber.Saints fought their way back into it and after Matty Smith went close following his own high kick, Richardson produced a moment of magic.He’d only been on the pitch a few moments when he took a pass around 10 metres out, dipped his shoulder and dummied his way over the line.It set up a mad final few minutes that saw Percival chip down the left hand side – the bounce alluding him – before he was wrapped up as Saints went for the wonder play as the hooter sounded.Agonisingly close once again for Holbrook’s side, leaving the match with Wigan on September 1 a must win.Match Summary:Rhinos: Tries: Hall, Cuthbertson Goals: Watkins (4 from 5)Saints: Tries: Lomax, Richardson Goals: Percival (3 from 4)Penalties Awarded: Rhinos: 10 Saints: 8HT: 2-8 FT: 16-14REF: Ben ThalerATT: 16,326Teams:Leeds: 31.
