Surrey became the first side to win a spot in the Clydesdale Bank 40 semi-finals by thrashing Leicestershire.
The Oval based county hammered their Group B opponents by 141 runs with England prospect Jason Roy smashing a second consecutive CB40 century – 131 from just 99 balls.
Rory Hamilton-Brown’s side remain unbeaten after 11 of their 12 group fixtures, with ten victories and one no result, assuring them a home semi-final spot.
They could be joined in the last four by last season’s runners-up Somerset and Sussex this week, with Durham, Nottinghamshire, Essex and Middlesex also still in the hunt.
The final takes place at Lord’s on Saturday 17 September, starting at 11:30am. Tickets are available now, (opens in a new window) starting at just £40 for adults and £5 for under 16s.
Many people will be installing Surrey as favourites to lift the trophy at Lord’s after a superb season in the 40 over game.
Hamilton-Brown and Coach Chris Adams have assembled a superb one-day outfit, packed with hard-hitting batsmen and relying on a number of spin options, including young Cambridge MCC Universities left-arm spinner Zafar Ansari.
England quick Jade Dernbach leads the seam attack, ably supported by Pakistani seamer Yasir Arafat.
The Surrey batsmen have been encouraged to attack throughout the competition, posting a highest score of 311 against Hampshire – amassed at the rate of 7.77 runs an over.
Hamilton-Brown and England wicket-keeper batsman Steven Davies form an explosive left-hand, right-hand opening pair.
England qualified youngsters Tom Maynard and Roy, who have both been selected for the England Development XI, are among those lighting up the middle order.
Roy stands just 28 runs behind Glamorgan’s Alvaro Pietersen in the list of top run scorers in the tournament and will hope to increase his case for a place in the full England team by topping the run charts.
