Leicestershire Foxes captain Josh Cobb hit a career-best unbeaten 67 to end Notts Outlaws’ 100% record in the Friends Life t20 clash at Grace Road.
Cobb led by example, clubbing seven fours and a six in his 52-ball innings, as the Foxes chased down a victory target of 159 with 14 balls and seven wickets to spare.
Bangladesh star Shakib Al Hasan struck a blistering 43 off 21 balls in a fourth-wicket stand of 67 with Cobb as the Outlaws lost for the first time in five games this season but remain top of the North Group while today's opponents sit fourth.
For once their powerful batting line-up failed to fire. Samit Patel top-scored with 50 off 32 balls yet the Outlaws could only post a below-par total of 158 for six after being put in.
Alex Hales and Michael Lumb started well when putting on 41 in the first five overs, with the latter hitting two sixes off Anthony Ireland.
However, once Lumb skied a catch off Rob Taylor on 23 and Hales edged behind off Shakib for 27, the momentum left the visitors' innings.
Patel and James Taylor, with 33 off 32 balls, did their best to step up the pace, although some tight bowling from Shakib, Cobb and Shiv Thakor kept the Outlaws in check.
Thakor, sending down accurate medium pace, dismissed Patel, Chris Read and Steven Mullaney to finish with 3-30 in four overs.
The last 10 sets of six only brought Nottinghamshire 69 and the Foxes made light work of the chase after a bad start when Greg Smith edged behind in Luke Fletcher's opening over.
Cobb and Joe Burns put on 55 before the latter, dropped when he had made just seven, was caught at cover off Mullaney for 26.
Niall O'Brien was stumped for 14 going down the pitch to left-arm spinner Graeme White but that proved to be the Outlaws' last success.
Cobb, dropped twice, made the most of his fortune by reaching his fifty off 38 balls, while Shakib hammered three fours and three sixes in his whirlwind innings.
Fittingly, Cobb struck the winning runs off the fourth ball of the 18th over to give the Foxes their second win in six games.
