Southern Brave 120 for 6 (Garton 28) beat Birmingham Phoenix 119 for 8 (Mills 3-20, Rehan 3-22) by four wickets
Brave climb to second in the table to boost their chances of reaching the playoffs whilst Phoenix remain bottom with progression looking unlikely.
Smeed crashed two glorious drives through the off side for four, and had a life when he was put down by Tim David in the deep, but his luck ran out when he was beaten by the extra pace of Mills and top-edged a pull to Leus du Plooy to leave the Phoenix 40 for one after the powerplay.
Brave captain James Vince turned to spin and was vindicated as Rehan trapped Jamie Smith lbw before bowling Duckett around his legs with a disguised googly.
Off-spinner Colin Ackermann picked up the prize scalp of Moeen with a jaffa as both spinners dominated, bowling back-to-back 10-ball sets.
Rehan picked up his third wicket after Dan Mousley overbalanced to a leg-side delivery and was smartly stumped by Devon Conway.
Livingstone was dropped in the deep and threatened to make Brave pay when he dispatched Rehan and Mills for sixes, however he soon edged behind off Mills.
In the final end Benny Howell fell to a Jordan slower ball and Chris Woakes holed out to long-off as Mills picked up his third wicket and Phoenix could only muster 119 for eight.
Allen fell soon after when he could only glove an attempted ramp off Kane Richardson to Smith.
Vince worked a Richardson in-swinger behind square for four off his first delivery, before assertively pulling Woakes to the boundary. However, the Brave’s captain was bowled after advancing down the pitch to an Ali delivery that spun between bat and pad.
Devon Conway was run out after a mix up, however a quickfire partnership of 44 between Garton and Du Plooy put the Brave firmly in control.
Garton fell after looping a catch to point, David holed out to cow corner and Du Plooy was trapped lbw without addition across six dot-balls, before Brave stumbled over the line for a vital victory.
