An MCC Young Cricketer in 2002, Peploe made his Middlesex debut in 2003 after impressing for the Middlesex Cricket Board.
The young slow left-arm bowler is also a useful lower-order batsman and will be hoping to gain a regular place in the Middlesex team.
He is no stranger to success at Lord’s, having once taken five wickets for MCC Young Cricketers against MCC.
He played in seven first-class matches in 2005, scoring 147 runs and taking 18 wickets.
However, he played in only one championship match in 2007, in which he took five wickets.
Peploe did not make any competitive Middlesex appearances in 2008.
