Pittsburgh Pirates hurler Dock Ellis thought June 12, 1970 was an off-day, so after a long night of partying he woke up and decided to take some LSD. What he didn’t know was he had slept through a full day and he was actually scheduled to pitch Game 1 of a doubleheader against the San Diego Padres.

But Ellis was able to not only secure a 2-0 Pirates win in San Diego, he held the Padres hitless in what is believed to be the only Major League no-hitter thrown by a man tripping on acid.

The story was long thought to be an urban legend, but Ellis talked openly about the experience in a 2005 Dallas Observer story. Ellis, who died in 2008, had long been drug free and was working as a drug counselor when he was interviewed for the article.

“What’s weird is that sometimes it felt like a balloon. Sometimes it felt like a golf ball,” the alternative weekly reported. “But he could always get it to the plate. Getting it over the plate was another matter entirely. Sometimes he couldn’t see the hitter. Sometimes he couldn’t see the catcher.”

That’s evident in the box score, as Ellis apparently walked eight and hit at least one batter.
