One of the most consistent bowlers in international cricket, Vaas relies on line and length to get his wickets but has the ability to swing and seam the ball to great effect.
He took 26 wickets against West Indies in 1994/95 and was the first bowler to take eight wickets in a one-day international - a feat he achieved against Zimbabwe, which included a hat-trick.
He took another hat-trick with his first three deliveries against Bangladesh in the 2003 World Cup.
He has taken over 300 wickets in both Tests and ODIs and is also a more than useful lower-order batsman.
He had a stint with Worcestershire in 2005 and also played for Hampshire in 2003, signing a contract with Middlesex for 2007.
Both his batting and bowling exploits came to the fore as he averaged 55.4 with the bat in the championship and took 20 wickets at 27.6.
He also topped Middlesex's batting averages in the NatWest Pro40 with an average of 54 from five matches.
