It's tournament time for Big 12 baseball, with 12 teams gathered in Arizona to play for a trophy ahead of NCAA tournament selection next week.
The conference has been highly competitive at the top this year, with Kansas the clear class of the field after clinching its first Big 12 regular season title in program history. West Virginia sits just a notch below them as a formidable threat, followed by a tight group of teams battling it out in the middle of the pack.
The top of the bracket features heavy hitters, with the top-seeded Jayhawks and the No. 2 seed Mountaineers entering as clear favorites to make a deep run. Defending tournament champion Arizona will miss the field entirely after failing to qualify, leaving the door wide open for a new champion to claim the crown.
Under the tournament's single-elimination setup, the top six seeds have earned an automatic double bye straight into Thursday's quarterfinals, while seeds 7 and 8 hold a single bye. But strange things have been known to happen in postseason baseball, and the Big 12 is always ripe for chaos.
Here's everything you need to know to tune in to every game this week.
