Kansas City has annually hosted men's basketball since 2010, and was already set for 2016 before the new multiyear agreement Thursday through 2020. The tournament was a sellout in each of the past two seasons, averaging more than 18,000 fans a game there.
The women's tournament was in Dallas this year, and it was previously announced Oklahoma City would host in 2016. Pending final negotiations, that will extend to 2019.
Baseball is returning to Oklahoma City next year, and Big 12 officials said final negotiations are pending for that to go through 2020.
