Pete Lovrich, who pitched for the Kansas City Athletics in 1963, passed away on December 26, 2018 at age 76.
Lovrich was the second player from Arizona State University to make it to the major leagues. He was soon followed by Vern Fuller, Rick Monday, Sal Bando, Reggie Jackson, and many others. (The Athletics really worked that school hard!)
Pete played for the A's class-C team in 1962, then made the jump to the majors in 1963, pitching in 20 games. Mysteriously, he was back in class-A ball in '64 and '65, then retired.
I was unable to find out any other details about him, but it seems likely arm injuries were the culprit, to have fallen that far, that fast.
