Waco, Texas

In the Big 12 Conference this college tennis season, schools are saying pish-posh to polite crowds and umpires who announce “Quiet, please!” at the slightest provocation. Tennis fans there have permission to scream, scream, scream—even during rallies and as players try to serve.

At Baylor last Friday, Nate Hilgenkamp, a 20-year-old religion major who wants to be a pastor, was excited to learn that the match between Oklahoma, the top-ranked team in the nation, and second-ranked Baylor would welcome hecklers.

“Oh, we got him! We got him!” Hilgenkamp shouted after a rattled Oklahoma player missed a serve.

“He’s got the yips! He’s got the yips!” yelled one of Hilgenkamp’s roommates, Chandler Wall, a 21-year-old Baylor junior.
