Nott Outlaws opener Michael Lumb missed a run out opportunity to draw the game, meaning Birmingham claim the one run needed to win the match by six wickets.
Birmingham started strongly as Ian Bell and Hain took 30 from three overs before the game was halted in light of Fletcher’s injury. After the resumption, Hain soon sliced Harry Gurney to point and Porterfield (20, 21 balls) ran himself out before Bell (47, 38 balls, five fours) lifted a reverse-sweep at Patel to Lumb at short third man.
Birmingham required 40 from the last five overs and Grant Elliott and Rikki Clarke took 15 off the first of them. Elliott’s 38 (22 balls, four fours, one six) saw his side to the brink of a victory but Notts dug deep and five runs from the last over, bowled by Christian, came down to one from the last ball, from which Colin De Grandhomme and Clarke scrambled the final single.
