For Opening Day, on April 6, the Astros hosted the St. Louis Cardinals. Nolan Ryan made his first Opening Day start for Houston; however, he took the loss as the Cardinals sent nine men to the plate and scored five runs during the first inning. St. Louis never looked back, pounding out 18 hits and taking the season's inaugural contest, 14–3. This was the first time that Ryan surrendered more than three runs in any game at the Astrodome. Art Howe banged out a sacrifice fly during the bottom of the second inning off Cardinals starter Bob Forsch and swatted a home run in the seventh. Alan Ashby also homered off Forsch in the sixth to account for all of Houston's tallies. Jim Kaat tossed a scoreless ninth inning for St. Louis to become the first pitcher in major league history to appear in 24 seasons. This was the second consecutive Opening Day that the Astros were matched up against that season's eventual World Series champions.

José Cruz smashed his 100th career home run on April 26, a two-run shot off John Martin of the St. Louis Cardinals. Ray Knight slugged a home run of his own, collected three runs batted in (RBI) and was 3-for-4 as Houston triumphed, 6–2. Nolan Ryan (1–4) went the distance, struck out five, and earned his first win of the season Cruz became one 31 Major League players through 1982 to accrue 100 home runs and 200 stolen bases or more during his career.

May On May 22, Terry Puhl connected for his first career grand slam, off Neil Allen of the New York Mets tying the score 5–5 during the bottom of the ninth inning. Puhl had three hits total, including a triple, and five RBI. The game proceeded into extra innings, and Allen remained in the game. While batting in the top of the twelfth inning, Allen reached on an error as the go-ahead run scored. Allen next tossed a scoreless bottom of the twelfth inning, retiring José Cruz on a groundout to end the game and preserve a 6–5 Mets win.

On May 26, reliever Frank LaCorte, after having walked the bases loaded to the Montreal Expos, became so furious that he torched his jersey upon returning to the clubhouse. LaCorte considered his jersey number 31 a bad omen, representing the many instances he had fallen behind in the count to the batter. The team later gave him number 27. George Cappuzzello relieved LaCorte, and all three runners scored—first on a sacrifice fly by Tim Raines, then on Tim Wallach's home run, rallying Montreal to a 4–0 victory in 10 innings. For the first nine innings, Charlie Lea had one-hit the Astros, while Don Sutton countered with five-hit shutout ball.

Don Sutton's 250th career win During his brief stay as an Astro, right-hander Don Sutton earned his 250th career victory on July 7, 1982, via a 5–1 tally versus the Chicago Cubs. It was his ninth win of the campaign. In support, Phil Garner slugged a two-run home run, and José Cruz drove in two others.

July From July 24 to August 14, Dickie Thon manufactured a 21-game hitting streak, which was the fifth in team history of 20 games or longer, and just two games short of Art Howe's then-club record of 23 from May 1 to May 24 of the prior campaign. During the streak, Thon batted .308, pounded eight doubles, three triples, and purloined eight bases, while striking out just twice. Thon's hitting streak tied Pete Rose for longest in the National League on the season, and tied for third longest in baseball behind Rod Carew (25 games), Kent Hrbek (23), and tied with Richie Zisk (21) in the American League (AL).

Nolan Ryan's 200th career win On July 27, Nolan Ryan earned the 200th victory of his career with a five-hit, 3–2 triumph over the Cincinnati Reds. Ryan whiffed 13, issued two bases on balls and earned a solid game score of 82. During the first inning, he picked off Eddie Milner. Meanwhile, Tony Scott doubled, collected an RBI, and swiped two of Houston's four bags. During the bottom of the eighth, Terry Puhl smashed a line drove of reliever Jim Kern, which second baseman Ron Oester slung wildly as Ray Knight charged around third base, ahead of the throw to home plate to score the winning run.

During the month of July, Ryan produced a 4–1 win–loss record (W–L), 1.10 earned run average (ERA), four complete games, and one shutouts in five games. Ryan surrendered, 25 hits surrendered, 13 bases on balls (BB), 0.927 walks plus hits per inning pitched (WHIP), while strikeout out 48.

August On August 11, Nolan Ryan hurled his first one-hit complete game as an Astro, the eighth of his career, and lowest-hit effort since his no-hitter on September 26, 1981. Ryan's most recent one-hitter was on July 13, 1979, as a member of the California Angels. Ryan (12–8) walked three and struck out six for a game score of 88, and, at the plate, hit an RBI single and drew a base on balls to lead a 3–0 win over the San Diego Padres. Terry Puhl slashed three hits, while Phil Garner and Ray Knight each logged RBI singles. The only hit Ryan surrendered was a single to center field by Terry Kennedy during the bottom of the fifth inning. Dickie Thon extended his hitting streak to 20 games.

On August 28, knuckleball specialist Joe Niekro (13–9) garnered his 100th career victory as a member of the Astros, leading a 2–0 defeat of the Montreal Expos. He went the distance with a six-hit shutout with four whiffs. In four previous outings on the season with Charlie Lea starting, Montreal had shut out Houston, while the Astros mustered 9 hits over the most recent three. In the fifth inning, Luis Pujols tripled in Art Howe for Houston's first run. In the eighth, a single by Thon, a wild pitch, followed by another single from Phil Garner accounted for the second score. A winner of 58 contests prior to joining Houston, Niekro followed Larry Dierker (137), J. R. Richard (107) and Don Wilson (104) as hurlers to win 100 games for the Astros.

On August 31, Ryan hurled a two-hit shutout of the New York Mets to lead a 4–0 Astros triumph. Ryan took a bid for a sixth no-hitter into the eighth inning, yielding a single to Ron Hodges for the first safety. The only other hit for New York was a single leading off the top of the ninth by Bob Bailor. Ryan retired George Foster on a groundout for the final out to secure the shutout. Ryan struck out nine, issued three base on balls and earned a game score of 89. Tony Scott hit an RBI groundout to score Dickie Thon for the game's first run during the bottom of the first inning. In the top of the seventh, Alan Ashby hit an RBI single, and Danny Heep followed with an RBI double.

During the month of August, Nolan Ryan went 3–0 W–L and 1.98 ERA over 7 starts, with three complete games and two shutouts. Over 54 innings, Ryan yielded 32 hits, 25 BB surrendered a .168 batting average against (BAA), and 1.043 WHIP, with 48 punchouts. Hence, Ryan was recognized as the NL Pitcher of the Month. Ryan succeeded J. R. Richard as the most recent Astro to win the award, who was named in April, 1980. In the months of July and August combined, Ryan posted a 7–1 record, 1.60 ERA, 7 complete games, and 3 shutouts. Ryan surrendered 57 hits and struck out 96 over innings pitched (IP).

September On September 6, Bill Doran made his major league debut. Doran went 0-for-3 in a 4-to-2 defeat to San Diego. During the bottom of the second inning, Doran grounded out in his first plate appearance versus Padres starter Chris Welsh (8–5), who earned a complete game victory. Alan Ashby (10) homered in the bottom of the fourth inning—also scoring José Cruz—to supply all of Houston's offense.

On September 27, switch-hitting catcher Alan Ashby became the 12th National League player—on the 17th occasion—and first Houston Astro to homer from both sides of the plate in the same game. However, it was Ashby's single to right in the top of the eighth which plated José Cruz for the go-ahead tally at 4–3 over the Padres. Two innings earlier, Ashby had homered from the left side off Padres starter John Montefusco to tie it 3-all. In the top of the ninth, from the right side, Ashby took lefty Chris Welsh deep for a three-run bomb for the 7–3 score. Houston batters aggregated 15 hits, led by Ashby and Cruz with three each. Meanwhile, Vern Ruhle (9–13) posted scoreless ball over the final five innings in relief, with four strikeouts to pick up the victory.
