Graeme Swann: Roy on fire but white ball form irrelevant for Ashes

Bangladesh should have stuck with spin

No surprise to see Bangladesh opening with spin at Cardiff after England's performance against Pakistan and the openers got lucky a few times in the opening overs, but Jason Roy had a word with himself and he and Jonny Bairstow then batted sensibly before cashing in when the seamers came on.

Bangladesh will probably look back and think they moved away from spin too soon, as Shakib was bowling really well, and the game really went away from them when the seamers came on.

I don't see other teams moving away from playing the spinners early against Roy and Bairstow - there were enough early wobbles to suggest they are not out of the woods there.

'Ludicrous' to pick an Ashes team on white ball form

Roy went on to hit a superb 153 of course and there has been plenty of talk about him playing his way into the Test team for the Ashes but I would never, ever pick a red ball team based on white ball form - it's a completely different game.

I'm not saying Jason shouldn't play as no-one is really putting their hands up for that opener role, but it's a ludicrous notion to pick someone for a Test side based on one-day form.

People will point to Jos Buttler as a 'success' story for picking someone on the basis of one-day performances, but while he has done an excellent job at number 7 it's been by playing in a traditional manner - he was actually brought in to be a 'game changer' in the lower middle order and he hasn't actually done that.

Windies missed out against Aussies but still dangerous

I mentioned West Indies as my best outside bet in my outright preview and, had they beaten Australia, they would have been bang in contention because of the confidence that would have been flowing through the team.

It was a game begging to be won after they had Australia at 79/5 and then a get-able 288 but the failure to chase down the total highlighted their lack of strength in depth compared to the tournament favourites.

It wasn't bowling that lost them the game - the Aussies will always be able to get some sort of score on the board - but the West Indies do miss Sunil Narine (whose finger injury precludes him from playing anything other than T20) as a top class spin option.

There's still a long way to go in the tournament so there is no need for West Indies to panic yet but, with only one win in three so far, they'll be focused for Friday's game with England and will be a dangerous opponent.

But as long as England maintain their fearless approach, they should have enough for victory - a score of around 310 would be defendable on what is a big Southampton ground, so not one for huge scores.

I'll back that man Roy again to continue his good form and top score for England, at 16/5. As for top bowler, with a bit of cloud cover in the air, I'll go for Chris Woakes, at 4/1. Jofra Archer has grabbed the headlines and rightly so, but Woakes is a top class bowler in his own right - and a good lad to boot - so that's where my money is going on Friday.

ICC need to rethink reserve day policy

We've already lost a record four matches to washouts and - India v New Zealand has been called off at the time of writing - so the decision not to have reserve days isn't looking too clever. I get that it's a difficult balancing act for the ICC but there is enough time between matches to fit in reserve days and it's something that needs to be looked at before the next big tournament.
