A last-ball six from Graham Clark saw Northern Superchargers defeat Southern Brave on their home turf in a nail-biting finish.Put into bat, the Brave were soon in all kinds of trouble. Kiwi Jacob Duffy, fresh off the plane from a Test series with Zimbabwe, decimating their power-packed top-order, reducing them to 26 for 3 off 24 balls by dismissing Leus du Plooy, James Vince and Jason Roy.James Coles and the evergreen Laurie Evans rebuilt steadily then violently, putting on 87 in 57 balls to put a defendable total in sight despite spin twins Mitchell Santner and Adil Rashid keeping things in check, the Brave finishing with a middling 139 for 5.Jacob Duffy celebrates an early breakthrough•Alex Davidson/Getty Images

Craig Overton replicated the work of Duffy, taking three relatively inexpensive wickets for the Brave, but Zak Crawley sparkled alongside England team-mate Harry Brook, both of whom scored quickfire 20s.When Chris Jordan pulled up with a groin injury, it felt like a game-changing moment but the Brave rallied, Jofra Archer bowling a brilliant penultimate set, going for just one run and taking two wickets to finish with 2 for 15.The Superchargers needed 10 off the last set, bowled by Tymal Mills. Dots off balls three and four left five needed off the last, at which point Graham Clark hit a back-of-the-hand slower ball over the ropes at deep midwicket to send the away fans into a frenzy.Clark, only playing due to a David Miller niggle, said he felt “euphoric” after sealing the points. “I thought I’d messed it up when I left that wide one and then missed a slot ball, but it’s such a good feeling to get over the line,” he said.”Batting in the middle order role is something I’ve never done before. I’ve spent the last few days with [batting coach] Neil McKenzie trying to improve my power-hitting. We thought it was a really good wicket, where you could play proper shots. Santner really took the pressure off: he’s a quality operator, when he fields, bowls or bats; such a calm character, and hits the ball so cleanly.”
