ROY AND EVANS SEAL SURREY'S HOME QUARTER
A chase of 160 on a slowing pitch looked a tough ask, but Jason Roy and Laurie Evans made it look a cakewalk. Kent Spitfires couldn't contain the two free-flowing batsmen, despite Roy taking a while to get into form. Once he did, it was an exhibition of divine batting, the pair adding 135 for the second wicket and crashing the ball to all parts of The Kia Oval. Surrey had already secured a quarter-final but this victory ensured it will be played on home turf.

STEELBACKS SHOW THEIR METTLE
The Steelbacks found themselves 71/6 chasing 192 to win, and staring down the barrel of a defeat that would eliminate them from the Vitality Blast. But against a Birmingham Bears side missing strike bowler Olly Stone, the visitors pulled off an extraordinary victory. Tom Taylor hit a rapid 50 from 27 balls on debut for the club, but he was outshone by his partner Graeme White, who struck an absurd 37 from 12 balls to send the Steelbacks to the quarter-finals.

SMITH ENSURES GLOS TOP SPOT
Gloucestershire didn't need to win to guarantee finishing top of the Central Group - thanks to Steelbacks beating Birmingham Bears - but they didn't know that. What they did know was that with one ball remaining, they needed three runs for victory. Enter Tom Smith, who had been at the non-striker's end for five balls without facing, and hit the final delivery to the boundary. 

FOXES HUNT DOWN LIGHTNING
Leicestershire Foxes had to take the points from Lancashire Lightning to qualify, and they did just that. Forties for Nick Welch and Arron Lilley set a defendable 154/5, and top order runs for Lancashire made it look a precarious task for the Foxes. But three wickets in an over for Colin Ackermann pegged back the hosts so substantially that Leicestershire took a fairly comfortable victory from Emirates Old Trafford, and a quarter-final spot.

SHAHEEN MADNESS
Hampshire have struggled to get going in this year's Vitality Blast but they saved the best performance to last. They set a meagre 141/9 against Middlesex but it was the bowling of Shaheen Afridi which handed Hampshire their second victory of the season. The Pakistan quick took 6 for 19, including four wickets in four balls to win the game, in a blistering display of fast bowling.
