In the inaugural season of the PKL, U Mumba were one of the must dominant teams in the league but lost the ultimate match of the competition, thus ending as runner's up to the Jaipur Pink Panthers. In 2015, they were out to make up for their mistakes and successfully won the tournament after defeating Bengaluru Bulls in the Final. Later next season in 2016(January), U Mumba lived up to the tag of the best team in PKL history and made their third successive PKL final before eventually ending as runner's up, as they were defeated by the Patna Pirates by a narrow margin despite a lion hearted comeback in the second half of the final.
Ahead of the 2016(June) season, in the PKL auction, U Mumba lost many of their key players who were a part of the squad that reached three consecutive finals. The team wasn't able to deal with the changes as they failed to make the playoffs in the following two seasons-2016(June) season and 2017. An inspired change of personnel by the owners ahead of the 2018-19 season, saw U Mumba regain their lost touch and qualified for the playoffs after two failed attempts. In the process U Mumba once again became the force they once were, and ended the league stage with dominant wins and the most highest score difference than any other team. But inability to peak in big games with narrow margins, saw them getting knocked out by the UP Yoddha in the playoffs.
