The 2007 Cricket World Cup warm-up matches were held prior to the 2007 Cricket World Cup, between 5 March and 9 March 2007. All 16 nations that were qualified to take part in the World Cup participated in a series of matches to prepare, experiment with different tactics and to help them acclimatise to conditions in the West Indies. The warm-up matches were not classified as One Day Internationals by the International Cricket Council (ICC), despite sharing some of main features of this form of cricket, but some of the playing regulations were different from standard internationals in order to allow teams to experiment. For example, the main change allowed for thirteen different players to play in a match – nine players being allowed to both bat and bowl, with two only being able to bowl and two only being able to bat – instead of the eleven players normally allowed. Several of the teams voiced concerns of various matters involving the stadia and practicing facilities: many of the stadiums were considered incomplete, whilst some teams claimed that the pitches were uneven, resulting in an unsafe experience to be batting in. Ultimately none of the stadia used in the warm-up games were used in any other part of the tournament except for the Greenfield Stadium in Trelawny, Jamaica, which hosted the opening ceremony but no matches. Australia, Bangladesh, India and Pakistan were the only teams to win both of their warm-up games, whilst Bermuda, Canada, the Netherlands and Scotland did not win either of their fixtures. Match status None of the warm-up games were officially recognised as ODIs or List A matches by the International Cricket Council due to various changes in the rules of the game. Whilst normally only 11 players are allowed to bat and field (excluding situations involving a substitute fielder), 13 players were used in each team's squad for the matches – 11 of which were allowed to field at one time and 11 of which were allowed to bat (meaning players could be swapped in and out when fielding or bowling, but two players did not bat in a match). In official ICC matches match referees are required to help officiate a game, but due to the changes in the rules none were appointed for any of the warm-up games. Additionally, Man of the Match awards were not given out and no reserve days were
