Yorkshire are relishing tonight’s Vitality Blast “straight shootout” with fellow contenders Nottinghamshire at Emerald Headingley, with quarter-final qualification the big prize on offer.

It is a winner takes all clash between the Vikings and the Outlaws (6.30pm).

Both sides sit on 14 points from 13 North Group games, with the Vikings just ahead in fourth place courtesy of a superior net run-rate.

In the unlikely event of a No Result or tie, that would mean they advance.

Yorkshire beat Northamptonshire at Wantage Road last night by seven wickets with 27 balls to spare chasing 163 thanks to a star display from captain David Willey.

Against his former county, Willey claimed 3-30 from four overs, including a triple wicket maiden in the penultimate over of the Northants innings.

He then crunched 79 off 44 balls, going on a run of hitting five sixes in 12 balls at one stage.

He shared 150 for the second wicket with Adam Lyth (66) after Josh Cobb had given the hosts a total of 162-8 with an unbeaten 68.

Champions Notts have come with a late run to stay in contention to defend their crown, including beating the Vikings at Trent Bridge last Friday.

“The result at Trent Bridge wasn't good, so it was important we bounced back given the importance of the two games,” said Willey.

“The way we played showed how much it means to us to progress in this competition.

“Going out there chasing 160, I felt it was important to kill the game rather than take it deep, to break the back and keep going really.

“Lythy and myself managed to do that, and it meant for a comfortable win in the end.

“It gives us some momentum with bat and ball going into Notts.

“Two teams, all to play for. They did us on their patch, so hopefully we can return the favour and get ourselves through to the quarter-finals. Then who knows what can happen?”

Yorkshire coach Andrew Gale said: “It’s a straight shootout now. We have a fantastic record on our home patch.

“We’ll have a good crowd in, they can be our 12th man. Hopefully we put on a good show and get over the line.”

“I thought 160 was about par,” he continued.

“I felt we bowled and fielded pretty well. We were intelligent with the bowling, and we communicated early on what sort of lengths we needed to bowl.

“Cobb played well, but we kept taking wickets, which was key.

“I knew if we had a good power play, that would break its back.

“Dave and Lythy were outstanding.

“I would describe that performance as very professional.

“They only got 35 off the power play, which was good for us.

“Ok, we dropped a catch which should have been taken. But that’s T20 - it can happen.

“Dave bowled well, Puds (Plunkett) and Fish through that middle period.

“We spoke at half-time about how the pitch was a bit tacky, so stick in and give yourself a chance. But it looked like it became a lot easier when you got yourself in.”

Willey added: “It was a pitch where if you go yourself in, there were balls which you could hit.

“The way Cobby (Josh Cobb) played showed that.

“Credit to our bowlers generally. I felt we bowled the right lengths and bowled to our field, which I don't think they did. We also tried to starve him of the strike, which worked well for us.”
