The online broadcast stream is free nowadays, BTW, in case you want the hometown call during the game. That is usually ahead of ESPN+, but can be paused to sync:

This was apparently a delayed decision. ESPN.com scoreboard did not indicate ESPN for the Big 12 games until yesterday. Guess they decided Big 12 games will draw better than ACC. Big 12 rules in this era!!
It will also be on ESPN+, along with the other 3 Big 12 Tournament games today:
