On May 26, 1959, Harvey Haddix threw one of the best games ever in the modern era. He retired 36 batters in a row - 12 full innings of perfect baseball. What’s more is he lost 1-0 [Boxscore]. He came to the Pirates from Cincinnati just before the start of the season.
The Reds traded Haddix along with Smoky Burgess and Don Hoak to the Pirates and got 4 players in return. Any trade with a “Smoky” and a “Whammy” in it is a winner. Lou Jackson spent some time in Japan. And I found this interesting article on Hopke from the January 1961 Baseball Digest.
