Only the one player made his major league debut as a Minnesota Twin on July the 9th. This debut is extra special however; because Ron Keller was the first player to be drafted and signed by the Minnesota Twins and make his big league debut wearing the colors of the Minnesota Twins.

Ron Keller (P) – July 9, 1966 – Drafted by the Minnesota Twins in the 8th round of the 1965 amateur draft. The Twins were already down 5-0 when Ron Keller was called upon by Sam Mele to relieve Jim Merritt. Keller had a clean first inning on the Met Stadium mound but then allowed 3 runs in the next inning including a home run by future Hall of Famer Al Kaline and kept the Tigers off the board in his third inning of relief.
