On June 5, 1966, at Forbes Field the Pittsburgh Pirates beat the Houston Astros 10-5, during the victory slugger Willie Stargell goes 5-for-5, includes two home runs and a double. The hitting spree gives Stargell nine hits in nine consecutive at-bats over the last two games.

In the same game Roberto Clemente hits his second 500-foot home run of the year. Les Biederman of The Sporting News describes it: “Clemente hit one ball between the Barney Dreyfuss monument and the right-center light tower – a rarity for a right-handed slugger. It traveled out of the park between the 436-foot sign on the right-center fence and the Barney Dreyfuss memorial to the left. The ball landed approximately 60 feet beyond the wall on a diamond where some youngsters were playing.” He adds: “The fans talked about this one for a long time, and it was such a shot that centerfielder Jim Wynn of the Astros stood with hands on hips and admired it for a few seconds.”
