Lose Jim Lonborg also threw a complete game, allowing the three runs on eight hits. Roger Metzget tripled in the first two runs for the Astros before coming home on Roberts's suicide squeeze.

St. Louis 3, New York 2: Alan Foster struck out 13 in his complete game. He allowed two earned runs on six hits. Ken Reitz drove in a pair of runs for the Cardinals with a double and a grounder. Bud Harrelson was injured and must sit out the first two games in Chicago,
