Seasons

The 1966 Houston Astros season was the fifth season for the Major League Baseball (MLB) franchise located in Houston, Texas, their second as the Astros, fifth in the National League (NL), and second at The Astrodome. The Astros entered the season with a 65–97 record, in 9th place, and 32 games behind first place in the National League.

The 1965 season was the first for Grady Hatton as manager, the third in franchise history, having replaced Lum Harris.

Though this was the second season for the Astrodome in operation, it was the first with the playing surface of AstroTurf installed. The infield portion was installed in March, and the outfield was ready for play on July 19.

The Astros' first round draft pick in the amateur draft was pitcher Wayne Twitchell, at third overall.

Second baseman Joe Morgan and pitcher Claude Raymond represented the Astros at the MLB All-Star Game, the first career selection for both.

The team finished in eighth place in the NL with a record of 72–90 (.444), 23 games behind the Los Angeles Dodgers.
