YORKSHIRE will continue to attack as they search for a route back into contention in the NatWest T20 Blast, starting against Nottinghamshire Outlaws at Headingley tonight.

Coach Jason Gillespie has told his players "we don't want to second guess ourselves now", having set on a brand new aggressive approach at the start of the tournament.

During pre-season, Gillespie wanted to get away from being a one-in-three side. By that he meant the Vikings, on average, only win one of every three Twenty20 matches they play – so he gave his players license to thrill.

It worked out well in the opening two matches, with wins against Derbyshire at home and Notts away. But they have lost their last three to undermine their chances of quarter-final qualification.

"We're sticking true to our game, which is we're looking to be aggressive and looking to go at the bowlers," said Gillespie.

"In the field, we're looking to be really aggressive as well. By and large, with our bowling, we've been looking to take wickets. We just haven't quite got the skills right.

"We're sticking to our plan. We don't want to second guess ourselves now.

"We have always said that we would rather get bowled out for 80 going for 180 than eke our way to 120, because you're not winning many games from scoring 120.

"But you're winning a lot of games when you're getting over nine an over. That's the way we believe we play our best cricket. We just need to go out there and do the job now.

"Regardless of past results, every team goes out to win every game they play. Notts will be no different; we're no different. It genuinely comes down to who performs the best across all disciplines on the day.

"It's not rocket science. If you bat well, bowl well and field well, you tend to come out on top."

Matthew Fisher returns to the squad, having missed the defeat against Northamptonshire on Sunday, and he should replace the rested Jack Brooks in the team.

Gillespie has also given struggling overseas batsman Glenn Maxwell his backing after four low scores since his fellow Australian arrived at Headingley from the Indian Premier League.

He said: "Maxi has been smacking them around in the nets. At training, and in team preparation, he has been absolutely brilliant. It just hasn't quite clicked for him.

"But we are fully expecting him to score those runs that he and the club are desperate for."

Meanwhile, Gary Ballance, Adam Lyth, Liam Plunkett and Joe Root have been selected in a 14-man England squad for a four-day pre-Ashes training camp from next Saturday.

The Yorkshire quartet will miss the LV= County Championship match at Durham, starting 24 hours later.

Root and Adil Rashid are in England's T20 squad for the clash with New Zealand at Old Trafford on Tuesday.
