The game on the field is regulated by the two umpires, one of whom stands behind the wicket at the bowler's end, the other in a position called "square leg" which is about 15–20 metres away from the batsman on strike and in line with the popping crease on which he is taking guard. The umpires have several responsibilities including adjudication on whether a ball has been correctly bowled (i.e., not a no-ball or a wide); when a run is scored; whether a batsman is out (the fielding side must first appeal to the umpire, usually with the phrase "How's that?" or "Owzat?"); when intervals start and end; and the suitability of the pitch, field and weather for playing the game. The umpires are authorised to interrupt or even abandon a match due to circumstances likely to endanger the players, such as a damp pitch or deterioration of the light.[67]

Ranji Trophy – Founded as the 'Cricket Championship of India' at a meeting of the Board of Control for Cricket in India in July 1934. The first Ranji Trophy fixtures took place in the 1934–35 season. Syed Mohammed Hadi of Hyderabad was the first batsman to score a century in the tournament. The Trophy was donated by H.H. Sir Bhupendra Singh Mahinder Baha-dur, Maharajah of Patiala in memory of His late Highness Sir Ranjitsinhji Vibhaji of Nawanagar, affectionately called as Ranjitsinhji. In the main, the Ranji Trophy is composed of teams representing the states that make up India. The number of competing teams has increased over the years. Some states have more than one cricket team, e.g. Maharashtra and Gujarat. There are also teams for Railways and Services representing the armed forces. The various teams used to be grouped into zones – North, West, East, Central and South – and the initial matches were played on a league basis within the zones. The top two (until 1991–92) and then top three teams (subsequent years) from each zone then played in a national knock-out competition. Starting with the 2002–03 season, the zonal system has been abandoned and a two-division structure has been adopted with two teams being promoted from the plate league and two relegated from the elite league. If the knockout matches are not finished they are decided on the first-innings lead.

In the approximate centre of the field is a rectangular pitch (see image, below) on which a wooden target called a wicket is sited at each end; the wickets are placed 22 yards (20 m) apart.[60] The pitch is a flat surface 3 metres (9.8 ft) wide, with very short grass that tends to be worn away as the game progresses (cricket can also be played on artificial surfaces, notably matting). Each wicket is made of three wooden stumps topped by two bails.[61]
