Umpire and MCC Laws sub-committee Member, Simon Taufel, stood in his 150th one day international - taking charge of Zimbabwe v West Indies in St. Vincent on 10 March.
Taufel made his international umpiring debut in 1999, standing in a match between Australia and Sri Lanka in Sydney.
He has stood in 61 Tests (3 Tests; 2 ODIs and 1 T20 match at Lord's) and is one of the most respected officials in the game, being named ICC Umpire of the Year every year since 2004-2008.
Speaking before the match Taufel said: "For me umpiring is about giving back to the sport and having a good match rather than any particular milestone - I go out to enjoy every match I stand in and do my best.
"I feel very fortunate to be doing something I really love within our great sport and I am lucky to have such a great support team behind me, led by my wife and family.
"There is also a strong team aspect to umpiring and I am grateful to my umpiring colleagues for their support over the years."
Student of the Laws
Taufel was invited to join the MCC Laws sub-committee in 2009. In May that year he umpired a match between the MCC and MCC Young Cricketers in one MCC's early trials of pink cricket balls.
Taufel's increasing wealth of experience has been invaluable to MCC who, as Guardians of the Laws of Cricket, are currently re-drafting the laws of the game.
"He's a real student of the laws." said MCC's Laws & Universities Administrator Glen Read.
"Simon has a real understanding of the game from the very top level down to parks and recreational cricket. His input has been of huge benefit to MCC."
