On June 12, 1970, Ellis no-hit the San Diego Padres, 2-0, in the first game of a two-game doubleheader at San Diego Stadium, while reportedly under the influence of LSD. After the Pirates had flown to San Diego on Thursday, June 11, Ellis visited a friend in Los Angeles and used LSD "two or three times." Thinking it was still Thursday, he took a hit of LSD on Friday at noon, and his friend's girlfriend reminded him at 2:00 p.m. that he was scheduled to pitch that night. Ellis flew from Los Angeles to San Diego at 3:00 p.m. and arrived at the stadium at 4:30 p.m.; the game started at 6:05 p.m.
