Don Schwall was a star athlete at the University of Oklahoma during the 1950s, but before he graduated, the Boston Red Sox lured him away from school with a $65,000 contract.

Schwall was an all-star as a rookie in Boston and later pitched parts of four seasons for the Pirates, from 1963-66. He still lives in the Pittsburgh area.

After playing six seasons in the big leagues, Schwall went on to have a successful career in finance, but he knew he had left behind some unfinished business.

Recently, he decided to finally finish what he started decades ago. So, he made a phone call.

“I was wondering where is my degree, so I called the university,” Schwall told KWTV-TV in Oklahoma City. “They said there was some foul-up with the classroom or something like that.”

Two weeks later, Schwall said the University of Oklahoma called back and admitted it had made a mistake. Schwall had earned his degree back in 1961.

“He said, ‘Unbelievably, you were right. You earned the degree and we’re mailing it to you tomorrow.'”
