On June 15, 1967 — Jimmy Wynn becomes the first Houston Astro to hit three homers in one game, becoming the first of only two Houston players to have accomplished the feat in the 34-year history of the Astrodome. In 1994, ‘Toy Cannon’s’ performance will be matched by future Hall of Fame first baseman Jeff Bagwell.

Wynn’s homeruns are three solo shots at during the 6-2 win over the San Francisco Giants. Bob Bolin and Bill Henry are his victims. Mike Cuellar strikes out ten to win his eighth of the year.
