Vijay Hazare Trophy

The Vijay Hazare Trophy, also known as the Ranji One-Day Trophy, was started in 2002-03 as a limited-overs cricket domestic competition involving state teams from the Ranji Trophy plates. It is named after the legendary Indian cricketer Vijay Hazare.

In the 2021 edition Vijay Hazare Trophy has been held and no Ranji Trophy has been held because of COVID-19.
Format.
Until the 2014-15 season, 27 teams are split into 5 zonal groups as follows:
After playing each team in the group once, the five winners and the best performing runner-up qualify for the quarter final stage directly, while the four other runners-up play in the preliminary quarter finals. The two winners of pre-quarter finals join the remaining six teams in the quarter final stage. From the 2015-16 to 2017-18 season, the zonal groups were replaced with 4 groups of 7 each.
From 2018-19 season, the teams were divided into 3 elite groups and 1 plate group. The 2 top elite group had 9 teams while 3rd elite group has 10 team. Plate group consists of 9 new teams. Teams are grouped based on average points in preceding 3 seasons.
Tournament history.
From the tournament's inaugural edition during the 1993–94 season through to the 2001–02 season, no finals were held, and teams consequently played only within their zones, with no overall winner named.
During the 2002–03 and 2003–04 seasons, a final round-robin stage was held for the top teams in each zone. Since the 2004–05 tournament, a playoff format including semi-finals and a final has been held, with varying formats.
