Mark Sowton: Can England have a better NRR than Scotland after their batting tonight?

It's a big if, obviously, but to give you an idea of the situation...

If England can do anything like Australia managed against Namibia on this ground two days ago - bowling their opponents out for 72 and chasing the target in 5.4 overs - then their net run-rate problems would likely be behind them.

They'd then just have to beat Namibia on Saturday and hope Australia beat Scotland to go through.

Over the next 40 overs and few days, you might hear a lot about net run-rate. Here's how that works...

Run-rate is the average number of runs scored per over by a team in their entire innings - so, for example, a score of 140 off 20 overs equals seven runs per over.

Net run-rate is calculated by subtracting the opposition's run-rate from the other team's run-rate.

The winning side will therefore have a positive net run-rate, and the losers a negative net run-rate.

In a tournament, net run-rate is worked out by taking the average runs per over scored by that team in each game and subtracting the average runs per over scored against them in each game.

If a team is bowled out inside their allotted overs, their run-rate is calculated by dividing the runs by the maximum overs they could have batted - 20 overs in the case.

Oman captain Aqib Ilyas: "We wanted to bowl first. It's a very good wicket, our batsmen will have to be confident.

"You have to learn from the games playing against these sides, we're getting the positives from these games. It's good for us.

"We can only improve the bowling and make sure our fielding is strong."

England captain Jos Buttler: "We're going to bowl first, it looks like a good wicket and we want to know how many runs we're chasing.

"We've been really focused on today with really good prep.

"We're going to try and earn the right to win the game. We have made one change Reece Topley. We hope he will bring early wickets and a bit of swing."

Here's how the Group B table looks coming into this one.

Australia are already guaranteed a place in the Super 8s, while Namibia and Oman are eliminated.

That means it is direct shootout between Scotland and England for the other place in the last eight.

Scotland will progress if they beat Australia on Sunday (01:30 BST), regardless of England's results. If they lose it opens the door for England.

However, England must win both of their games against Oman on Thursday and Namibia on Saturday (18:00 bst) and overturn the net run-rate difference between the two sides to progress, regardless of Scotland's result.

England have made one change. Reece Topley comes in for Chris Jordan.

That's a smart move, I reckon. Oman's top order have struggled against left-arm pace so far in the tournament.

First job done.

Jos Buttler has won the toss and decided the best way to go about this scenario is to bowl first.

Knock Oman over quickly and chase it as quickly as possible is the plan...

England have moved on from the party island of Barbados to the tranquility of Antigua with their World Cup hopes in real jeopardy.

Today they play Oman at the Sir Vivian Richards Stadium in their penultimate match.

They have to win to have any chance of pipping Scotland to progress. Realistically need to do so by a big margin.

Here comes the toss...
