'Fearless' approach is West Indies' plan in knockout semi

West Indies captain Hayley Matthews has vowed to step up and ensure that her side takes a 'fearless' approach into their crunch semi-finals showdown with Australia at the ICC Women's T20 World Cup.

Their clash at The Oval in London marks the all-or-nothing knockout phase of the tournament, with the winner booking a spot in Sunday's title decider at Lord's.

Australia are unbeaten, winning all five group games. The West Indies overcame Sri Lanka, Scotland and New Zealand to book their semi-final qualification, despite losing to England and Ireland on the run into the knockout phase.

Matthews confirms that the West Indies are leaning into an underdog mindset that sets them up to play a fearless brand against the Aussies.

"We're really excited as a group," she told media.

"We have nothing to lose, and that puts us in a position where we can be quite fearless going out there. You can't take your foot off the gas at any point in time, I think, especially when you're bowling. They seem to come hard from ball one and have a mantra where they just want to keep going. I certainly feel as though that keeps you in play a lot when it comes to having the opportunity to possibly take wickets."

"Coming up against a team like (Australia), who we know has a bunch of great players and superstars, we're going to have to have somebody stand out and do something special, but also have a lot of different people from the team contribute. We have a lot of match winners."

Matthews hasn't shied away from the pressure of needing to be one of the West Indies' standout performers.

"We haven't had the likes of myself or Deandra Dottin in the runs really —  and that leaves a lot of room for improvement for us as a team," she continued.

"So hopefully we can see some of us stepping up a bit more and taking it to the Aussies.

"We're going to need big performances from big players. To beat a team like Australia, you still need more than one player, and we're going to have to have our best players really stepping up to the plate tomorrow."
