John Francis Paciorek was born on February 11, 1945, in Detroit, Michigan.
John played baseball at St. Ladislaus High School in Hamtramck, Michigan, and signed an amateur free agent contract at age 18 with the Houston Colt .45s.
After a summer in the Houston farm system, John made his big league debut on September 29, 1963, the final day of the season.
That one game John went 3/3, with 3 singles, 3 RBI, 2 walks, and scored 4 runs, in 5 plate appearances.
A perfect line score... 3/3... a 1.000 batting average.
In right field John caught two fly balls in his only two fielding chances.
John fought injuries after that one day in the big leagues, and finished playing baseball in the minors until he retired in 1969.
Jim Paciorek, the only player in big league history with a perfect batting average, slugging, and fielding percentage.
John Paciorek...the Perfect ballplayer.
I must admit that I knew of John Paciorek mainly because if his brother, Tom Paciorek, who I remembered playing for the Mariners and White Sox.
John's brother Jim Paciorek also played big league baseball.
I also heard John Paciorek on TV this morning on Hot Stove, on the MLB NETWORK, and that led me to write today's HBB post.
I also saw that there's a book, Perfect, by Steven K. Wagner, and its definitely on my must read baseball book list.
John went to the University of Houston, and has a terrific blog on coaching and teaching at johnpaciorek.com.
John teaches physical education at a private school in California, and is the author of two books, "Plato & Socrates,"
and "Principles of Baseball."
Happy Baseball Birthday John Paciorek!
