Chief executive Mark Arthur says Yorkshire will only play with one overseas player during next season’s NatWest Twenty20 tournament.

Kane Williamson has been signed up as the county’s full-time overseas player, allowing him to take part in all competitions.

But the White Rose side will pass up the opportunity to supplement the New Zealander’s capture with that of a specialist Twenty20 signing such as South African ace David Miller, who was missed so badly during the 2013 campaign.

That is not to say Miller’s return to Headingley in 2014 has been completely ruled out because Williamson is expected to be missing for up to two months as the Kiwis have a tour to the West Indies pencilled in between mid-May and mid-July.

If Williamson travels to the Caribbean, Yorkshire will then look to employ a replacement overseas player who is more suited to 20-over cricket.

“We’ve already got Kane Williamson signed up and he can play in all forms of cricket,” said Arthur.

“If Kane is missing, we will look to bring in somebody to plug that gap. What I won’t do is bring in a second overseas man because we don’t have the financial resources to do that.

“We have to give ourselves every opportunity, obviously. Miller was a miss this year but Kane will be our overseas player for the whole season.

“If he has to go to the West Indies on tour with New Zealand, we will probably look to bring in a T20 specialist if one is available.

“What you also have to understand is that we have a very special dressing room and we want to bring the right person, as well as the right cricketer, in because the camaraderie there is the best I’ve seen in 23 years of professional sport.”

Yorkshire only won five out of 22 matches in both forms of limited-overs cricket during the most recent campaign.

But Arthur is confident of an improvement next summer, especially given that 50-over cricket will replace the YB40 competition.

“On the one-day game, I think we all admit we came up short,” he said.

“There were very fine margins in the T20 version and we’ll be looking to improve next year.

“We also believe we’re probably better suited, with the squad of players that we’ve got, to the 50-over game than we were to the 40-overs.”
