PAT Brown is working on developing new deliveries for his considerable Vitality Blast armoury as he looks to repeat the success which helped Worcestershire achieve title glory last September.

But he does not want to be pigeonholed as a T20 specialist and is also keen to make an impact in red-ball cricket.

Brown played four of the final five games in the County Championship Division Two promotion-winning season of 2017.

But for now the focus is on the Blast with Rapids heading to Emirates Old Trafford to face Lancashire Lightning on Friday (6.30pm) and then hosting Durham on Sunday (2.30pm).

Brown took 31 wickets in last season’s T20 — the most in the country — and only a back injury prevented him from playing in last winter's Bangladesh Premier League.

He said: “I’ve worked on a couple (of deliveries). You’ve got to keep trying to evolve your game and stay one step ahead.

“I’ve not bowled them in a game yet but I don’t think it will be too long before I can.

“I’ve been practicing them for a couple of weeks now so when we get into this T20 block of cricket it will be easier to practice them more consistently and get to where I want to be with them before I bowl them in a game.”

Brown is unfazed by opponents making use of the raft of technology available to try to counteract his bowling skills.

He said: “I’m sure they were last year as well. It’s not like it is a quick tournament over in a short space of time.

“It spans a long period and I’m pretty sure by finals day Lancashire and Sussex would have looked at some footage.

“I don’t worry too much about that. Like people say, even if you pick it and know it is coming you’ve still got to be able to hit it for six.

“If I can nail my skills like I know I can as well as I did last year I’ll be alright still.”

Brown appeared in Rapids' winning Blast opener at Notts Outlaws live on Sky Sports and took the challenge in his stride.

He said: “Did I feel any extra pressure? A little bit yes but I think it is mostly from myself now, more expectation than pressure, because I really want to perform like I did last year.”

Brown helped Rapids beat Lancashire and Sussex on finals day in last year's T20 success.

He said: “It is something to look back on with pride and a lot of pleasure with having won the competition as well.

“It is even more special knowing that I’ve contributed to something far greater than my own success."

On making his mark in the Championship, Brown added: “It is a bit frustrating that people try to pigeonhole me already as a T20 bowler.

“It’s a compliment in a way because of how well I went last year and that they think I’m good enough just to focus on white ball.

“But I’m a 20-year-old lad and have not really had a good run of games in red-ball cricket, partly due to my own performance, my back injury and lack of opportunities.

“There is plenty of time to improve in red-ball cricket and there’s no reason why I wouldn’t want to.”
