Gary Wheelock played some games for the Angels in 1976, and he played for the Mariners in 1977 and 1980. He kindly took the time to send me a brief note recently!
He let me know that Sandy Koufax was his favorite player.
I asked him about playing for the Spokane Indians specifically, and he said that it was a pretty city with good fans.
He also mentioned that his favorite baseball movies were "Field of Dreams" and "Damn Yankees".
