Warwickshire 288 for 6 (Smith 130*, Rhodes 75) beat Worcestershire 286 for 9 (Libby 112, Pollock 54, Rae 3-54) by four wickets

Early wickets then put Worcestershire in command but 19-year-old Smith played with freedom, fluency and not a trace of nerves to book his side a semi-final in south Wales.

Put in on a used pitch, Worcestershire openers Pollock and Gareth Roderick added 38 in ten overs before two wickets fell in five balls. Roderick was lbw to Rae and Rob Jones edged his second ball behind to reward Ed Barnard for an excellent opening spell.

Pollock advanced to a 54-ball half-century against his former team-mates but added only four more before slicing a drive at Jake Lintott to point. Adam Hose, freed from Hundred duty, soon spliced Michael Booth to extra cover but Libby reached his sixth half-century of this year's tournament (from 67 balls) and celebrated with six over mid-wicket off Barnard.

The captain received important support from Ethan Brookes and Tom Taylor in stands of 61 in ten overs and 28 in 18 as the pitch flattened out in the sunshine. Fateh Singh and Tom Hinley also cleared the ropes to lift Worcestershire to a strong total.

They also started strongly with the ball, taking two wickets in the first five overs as Theo Wylie skied Harry Darley to mid off and Zen Malik off-stump was trimmed by an inswinger from Taylor.

Barnard and Rhodes took the score to 50 before two big wickets fell in the 14th over. Barnard flicked Jack Home straight to midwicket. Three balls later, Michael Burgess was run out by a direct hit from Brookes.

When Benjamin edged a cut at Brookes, Warwickshire were 77 for 5 but Rhodes and Smith were unfazed. While the former captain anchored the fightback, Smith raced to a maiden List A half-century and then onward to a scintillating ton off 89.

The sixth-wicket pair had put their side in control by the time Rhodes was brilliantly caught by a sprawling Brookes from a skier. That left the Bears needing 29 from four overs and Smith and Lintott closed the game out nervelessly, Smith striking Taylor for six and four from successive balls to seal victory.
