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

But the 20-year-old does is also keen to eventually make an impact in red ball cricket.

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

For now the focus is on the Blast with Worcestershire able to now fully concentrate on the defence of their title after this week’s Specsavers County Championship encounter with Gloucestershire at Cheltenham.

Brown picked up 31 wickets in last season’s competition – the most in the country – and only a back injury prevented him from playing in the Bangladesh Premier League during the winter.

The fact his success helped the County pick up a trophy was more important for Brown than personal glory but he is aware of the need to continue to evolve his skills in white ball cricket.

Brown 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 and work out and counter-act 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.

“To be honest, 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.

“I don’t worry too much about if they are looking at what’s going to come or if they are looking too much into me.

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

Brown was firmly under the media microscope when he appeared in the Rapids opening Blast encounter against Notts Outlaws televised live on Sky Sports but 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.

“I didn’t feel much pressure from the outside, it was more from within to perform because I really want to perform like I did last year.

“Now I’ve done it last year I know I can get to that level and there is more pressure from myself to be want to be at that level again.”

Brown obtained the most pleasure from last heroics in contributing to tangible success for the County via the semi-final win over Lancashire and final triumph over Sussex.

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.

“The most pleasure I take is knowing my success contributed to an even greater success in us winning the competition.

While the Blast is now fully the attention of Brown – and his team-mates – he is keen to make his mark in the Championship.

He said: ““It is a bit frustrating that people try to pigeon-hole 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 for me, the way I see it, I’m a 20-year-old lad and I’ve 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 the red ball cricket and there’s no reason why I wouldn’t want to.”
