1993 Houston Astros season

The 1993 Houston Astros season was the 32nd season for the Major League Baseball (MLB) franchise located in Houston, Texas, their 29th as the Astros, 32nd in the National League (NL), 25th in the NL West division, and 29th at The Astrodome, The Astros entered the season as having finished in fourth place in the NL West with an 81–81 record, 17 games behind the two-time defending division-champion and NL pennant-winning Atlanta Braves.

On April 5, pitcher Doug Drabek made his first Opening Day start for the Astros, who hosted the Philadelphia Phillies but were defeated, 3–1. The Astros' first-round draft pick in the amateur draft was pitcher Billy Wagner, at 12th overall.

Right-hander Darryl Kile represented the Astros at the MLB All-Star Game, his first career selection. On September 8, Kile tossed the ninth no-hitter in club history in a 7–1 triumph over the New York Mets. This was just the 14th non-shutout complete game no-hitter in the major leagues.

The Astros concluded the season with an 85–77 record, an improvement of six games from the season prior, in third place and 19 games behind first-place Atlanta, who repeated as division champions for a third consecutive season. Hence, it was the start of the longest period of consistency of winning seasons for Houston, doing so in 14 of a span of 16 seasons through 2008, while claiming a playoff berth six times. It was also the start of an unprecedented seven consecutive winning seasons for the Astros, through the 1999 season.

This was the final of five seasons with Art Howe as manager, among other significant changes. It was also the final season that the Astros wore their "tequila sunrise" rainbow uniforms. As part of the league's playoff expansion by re-introducing the Division Series, it was the final time the Astros occupied the NL West division and would move to the newly-commissioned NL Central the following season.
