1969 – Larry Dierker becomes the first Houston pitcher to reach 20 wins in a 2-1 victory at San Francisco. Jim Wynn and Doug Rader homer off Gaylord Perry for the decisive runs. For Giant fans, the chance to see Willie Mays hit his 600th homer is the big attraction but Dierker and Jim Bouton limit him to a single and two walks. The Astros are five games over .500 and 5-1/2 games out of first.
