David Wainwright has got to regain his form and confidence pretty quickly because we are coming to the business part of the season for any spinner.

Now is the time when counties – not just those who have an embarrassment of riches in that department such as Yorkshire – start to think about playing twirlers in tandem because the pitches are becoming drier and drier.

Wainwright revealed in Saturday’s T&A how a winter away with the ECB’s Performance Programme squad and then the England Lions squad had him changing his mechanical action.

They were no doubt just a few tinkers here and there but they have amounted to a knee injury which has dogged him since the pre-season tour of Barbados, resulting in just 17 wickets in all forms of cricket this season.

Now he is at a crossroads in his career because he needs to play as much first-team cricket as possible to regain the form he showed last term.

But can Yorkshire risk playing a player who is now somewhat of an unknown quantity when they are gunning for the LV= County Championship title?

I guess now is the time when we will see just how far a county is prepared to go to produce an England player, which is virtually what Wainwright was in the winter.

He only just missed out on a place in England’s World Twenty20 squad!

Perhaps the most notable example of a player going to England, having his action changed and getting injured as a result is Jimmy Anderson.

He ended up with all sorts of back problems as England tried to make him more open chested in his action but now he is back to how he used to be and has blossomed into one of the world’s finest swing bowlers.

Okay, maybe there are no action issues with Adil Rashid but he has not been treated the best while with England, has he?

Now, following a prolonged spell as a glorified drinks waiter, he is back playing cricket with Yorkshire and things are looking pretty good again.

As for Wainwright, it sounds as if he has been sent back to Yorkshire with no dialogue between the two coaching staffs as to how the changes will benefit his long-term development.

He said that the changes, which were designed to make him more aggressive at the crease, all made sense on paper.

But the long and short of it is that they have caused his four-month injury nightmare.

So, in the long term he has got to find a way of marrying some of what the England coaches have told him alongside what he has done in his youth and with Yorkshire so successfully.

In the short term all he can do is try to stay fit and get out in the middle in his Yorkshire shirt.
