All-rounder Brett D'Oliveira has signed a new three year contract with Worcestershire and now is eager to "stamp my authority" on a place in the side in all formats of the game.

Leg-spinner-opening batsman D'Oliveira had one year remaining of his current deal but has put pen to paper on a contract until the end of the 2018 campaign.

Twenty-three-year-old D'Oliveira has joined Joe Clarke, Ed Barnard, Joe Leach and Tom Fell (three years) and Ross Whiteley (four years) in making a long term commitment to the County.

D'Oliveira became the third generation of his family after grandfather Basil and his father Damian to play for the county when making his debut against Yorkshire in a List A match at Headingley in 2011.

His first class debut followed in 2012 against Warwickshire in the County Championship match at Edgbaston.

D'Oliveira has made his mark in NatWest T20 Blast cricket this season and was the County's most economical bowler in the run to the quarter-finals.

But he has also forced his way into the Championship side in the latter part of the season as an opening batsman in place of Richard Oliver – a role he has occupied for the Second Eleven.

D'Olveira said: "I am absolutely delighted to sign for three years for the club. Moving forward it should be a good three years.

"There are six of us signed up now and it stands the club in good stead, all us young lads together, so hopefully in the years to come, we can kick on and start winning some trophies.

"It is a great bunch of lads, it's the city that I'm from and it's the club I love playing for. I'm very passionate about the club and want to win games of cricket for Worcestershire.

"It's been nice to get a few games this year. I've done well in the T20 and got into the four-day team.

"I just need to stamp my authority on it now so hopefully the end of this season and the start of next season, I will do that."

Director of Cricket Steve Rhodes said: "Delighted Brett has signed a new three year contract. He would admit he is still desperate to crack it at first team level.

"He is playing at the moment in all formats and that's for two reasons – a) he has performed in second team cricket and b) he has got three strings to his bow.

"He is one of those lucky players who is a batter, a bowler and an excellent fielder.

"That is not always easy though because those type of cricketers have to work extremely hard to make sure in all three disciplines they are up to speed.

"Brett is part of a famous cricketing family but in his own right, he is a worthy cricketer. Brett is very much his own person now and he is responsible for his own career.

"Hopefully everything is going to go well over these next three years and we can see someone who can really maintain a place in first team cricket and do well."
