Middlesex batsman-wicketkeeper Adam Rossington has signed a one-year extension to his contract.
The 18-year-old academy product played in four FL T20 matches last season, averaging 6.75 with the bat.
The England Under-19 player also featured in Sri Lanka's tour match against Middlesex.
Managing director of cricket Angus Fraser said: "Adam is one of the most promising young batsmen-wicketkeepers in the country."
Fraser added: "He showed us all the brand of cricket he is capable of playing on several occasions in the second 11 in 2011 and he has the potential to become a fine player."
