London:West Indies wicket-keeper Denesh Ramdin believes it is imperative they dominate Sri Lanka's unusual spin attack if they are to win Friday's World Twenty20 semi-final at the Oval.
Muttiah Muralitharan and Ajantha Mendis have posed numerous problems for batsmen during Sri Lanka's unbeaten run to the last four while round arm fast bowler Lasith Malinga has also been in the wickets.
"It's very rare you get two world-class spinners like this in the same side," said Ramdin.
"We want to get on top of them early so their captain has to take them off and bring them on later, so our plan is to get on top of them as they come on to bowl."
Ramdin added the key to playing Mendis, who flicks the ball off his fingers, was to treat him as a seamer.
"He's a mystery spinner, but as a batsman you just go out there and try and play each ball on merit," said West Indies' vice-captain.
"He's not spinning the ball as much as everyone expected so what we're trying to do is play him as medium pacer, hit him down the ground for ones and twos and wait for the bad ball.
"Their bowling line-up is quite tricky with Murali, Mendis and Malinga but we have to try and back ourselves."
Whoever comes out on top at the Oval will face the winners of Thursday's Trent Bridge clash between Pakistan and South Africa in Sunday's Lord's final.
