Ravi Bopara produced England's best ever Twenty20 bowling performance to set up a crushing 10-wicket win over the West Indies in the first game of a two-match series at the Oval Friday. The Essex all-rounder took 4-10 with his medium pace, eclipsing the previous best mark of 4-22 jointly held by Paul Collingwood and Jade Dernbach, as the tourists slipped from 52-0 to 125 all out. World champion England then cruised to victory, with 28 balls to spare, Alex Hales making 62 not out and Craig Kieswetter unbeaten on 58. The West Indies got off to a flying start but the introduction of the slower bowlers — Samit Patel (2-23), captain Graeme Swann (1-30) and Bopara — stalled the run rate and a rash of wickets saw the tourists collapse from 97-2 to a below par total. But their captain Darren Sammy did not seem to heed the lessons of his side's innings and didn't introduce his slower bowlers until the eighth over. By then England was 66 without loss and had the game under control. Hales passed 50 from 36 balls and Kieswetter did the same shortly afterwards taking 41 deliveries and England passed 100 in the 12th over on their way to a convincing win. It had seemed a different story when West Indies had been put in by England's stand-in captain Graeme Swann. They raced past 50 in 35 balls with Dwayne Smith helping himself to 20 off one over from Tim Bresnan before the spinners arrived and put the brakes on the scoring rate. With one over of the batting powerplay left Swann opted to give Patel a bowl, rather than having an over himself, and was rewarded with the wicket of Smith who was bowled for 33 by a ball that turned past his outside edge and hit off stump. Johnson Charles made 33 and Danza Hyatt 26, but the rest of the West Indies batsmen failed to make double figures.
