Roy scored 677 runs at an average of 48.35 in the T20 Blast this year

Surrey batsman Jason Roy has signed a new three-year contract, keeping him with the county until the end of 2017.

The 24-year-old, who came through the club's academy, was the leading run-scorer in the T20 Blast this season and has been called up to England's Twenty20 squad to face India on Sunday.

"It is exciting times at the club," Roy told BBC London 94.9.

"The nucleus of the squad has grown up playing together and we will be looking to win some silverware."

South Africa-born Roy made his first-class debut for Surrey in 2010 and scored over 700 runs in one-day competition for the side in 2013.

He has impressed again in one-day competition this season, with his 677 T20 Blast runs coming at an average of 48.35 and a strike rate of almost 160.

Roy has also scored 839 runs in Division Two of the County Championship this year, at an average of 52.43.

The former Whitgift School pupil featured for England Lions in last month's triangular series against New Zealand A and Sri Lanka A.

Surrey director of cricket Alec Stewart said he was "delighted" to see Roy commit his future to the side.

"Jason has had an excellent season in all forms of the game, culminating in his deserved call up to the England squad for the T20 against India," Stewart said.

"With his continued work ethic and improvement, I would hope to see him playing other formats of the game for England very soon."

Meanwhile, Roy is excited by the prospect of making his full international debut at Edgbaston on Sunday.

"It is going to be amazing and a whole new experience," he said.

"It has been my dream to play for England ever since I started playing. We'll see what Sunday holds for me."
