Yorkshire batsman Joe Root, who is centrally contracted by England, has extended his deal with Yorkshire until the end of the 2016 season.
He has hit 2,138 first-class runs for the county at an average of over 43.
Root, 23, has played in 15 Tests since making his debut in December 2012.
"He is one of the brightest talents in the game and will be part of Yorkshire and England's plans for many years to come," director of cricket Martyn Moxon told the club website.
"His desire to be the best that he can is a perfect example to our young players that if you work hard on your skills and have total commitment you can achieve almost anything in your profession.
"He is only 18 months into his England career and is already an established member of the national side."
Root is currently out with the fractured thumb that saw him miss the ICC World Twenty20 but should return in Yorkshire's County Championship match against Middlesex, which starts on 27 April.
