McCullum: England must 'find ways to deal with' packed schedule

England will go into their T20I series against South Africa without both Ben Duckett and Jamie Smith this week, prompting head coach Brendon McCullum to concede they must learn how to cope better with their busy international schedule.

Duckett, Smith and Harry Brook have been ever-present for England across their 15 international fixtures to date this summer, and all spent August playing in the Hundred. All three players will miss next week's brief tour to Ireland, and McCullum has prescribed an additional week's rest for his ODI openers so they can "freshen up" ahead of a busy winter away.

It means that Duckett and Smith will miss consecutive T20I series less than six months out from a World Cup in the format, when better planning would have seen them skip the ODIs instead. In their absence, Phil Salt - who missed England's most recent T20Is on paternity leave - looks set to open the batting alongside either Tom Banton or Will Jacks.

England face a tight turnaround between the Ashes and the T20 World Cup this winter, interspersed with white-ball tours to New Zealand and Sri Lanka. Rob Key, England's managing director, claimed last year that their upcoming schedule was "easing" when expanding McCullum's role to cover white-ball cricket but it shows few signs of doing so.

A one-day gap after the Hundred final meant that England's players did not train together as a full squad ahead of Tuesday's first ODI in Leeds, in which they were thrashed by seven wickets. ECB chair Richard Thompson acknowledged the crammed fixture list was an issue on Sunday, but admitted that it is unlikely to change significantly within the ongoing broadcast rights cycle.

"The scheduling isn't ideal," McCullum said after England's consolation win in Southampton. "That's just the way it is and it's not going to change, so we're going to have to find ways to deal with it… We're just going to have to find ways to be able to hit the ground running a bit quicker than what we did in this one.

"I spoke to [Duckett] and I said, 'I think you need to freshen up. You've played so much cricket and you're such an influential player for us over the next few months.' He'll have a decent break at home, as will Jamie Smith… It gives the other guys opportunities, and it's exciting, too. If we just rely on 11 players, then we're not really going to be competitive."

One of those "other guys" is Sam Curran, who will bat in the top six against South Africa after winning a recall through his performances for Surrey and Oval Invincibles. McCullum has never previously picked Curran for one of his teams, and told him in an "honest conversation" over breakfast earlier this summer that he needed to "bang the door down" as a batter.

"The message to Sam was that a lot's come to you quickly and you've had a lot of success and a lot of fame, and a lot of things have fallen your way," McCullum said, "but, of late, your performance had just tailed off a bit… With us resting both Jamie and Ben, it gives us the opportunity to bring Sam in and he'll get his chance to bat in the top six."

England are expected to stick with the spin-heavy strategy they trialled against West Indies in June for this week's series as they prepare for next year's T20 World Cup in India and Sri Lanka. Curran will likely be their third seamer, with Jacob Bethell and Jacks supplementing Adil Rashid and either Liam Dawson or Rehan Ahmed as spin options.

Bethell and Jacks acted as England's fifth bowler in the ODIs against South Africa but their combined 10 overs in a tight defeat at Lord's were hammered for 112 runs. McCullum said it was "really hard" to balance the side without a genuine allrounder, but has already spoken to Brook about how to give his part-time options "slightly more in their favour".

"We've just got to be a bit smarter with it… Utilising the big side of the ground, or also trying to set slightly more defensive fields," McCullum said. "They don't need to take 3 for 30 off 10 overs. They've just got to find a way to be able to create pressure and hold for a period so that our attacking guys can come in.

"We won't always be married to that [balance] but at the moment, we want to make sure that we've got that familiarity within our batting group - particularly in the middle order, as they adjust to some new roles so that they get more and more comfortable with how each of them is going to play."

McCullum said that England's record 342-run thrashing in Southampton had provided them with "an incredible blueprint" in ODIs during an "oscillating" series. "We got hammered in the first one, we were within one blow in the second, and we dished out a pretty good performance in the third… It shows that there's not a huge gulf between the two teams."
