The Astros played Opening Day on April 6 at Atlanta Stadium, where they defeated the Braves, 2–1.

Astros Opening Day starter Dave Roberts lasted the first nine innings, scattered eight hits, and allowed one run.

Starting April 9, Bob Watson authored a career-high 19-game hitting streak, batting .388. The streak lasted until April 27.

The first-ever Player of the Week Award was presented for the National League by president Chub Feeney to Astros left fielder Jimmy Wynn for the week ended April 16, 1973. Considering the 11 games played since Opening Day on April 6, Wynn connected for 6 home runs, 10 RBI, one double, one triple, and had carried a batting average of .313 (15-for-48).

May For the week of April 27 to May 3, Bob Watson batted .333 over five games, with three home runs, six RBI, an .833 slugging percentage (SLG). The terminus of his 19-game hitting occurred on April 28, when Watson went 0-for-4. The following day, he hit two home runs to lead a 4–3 triumph over the Montreal Expos. Houston won each of the five contests. Watson won the fourth NL Player of the Week honors, succeeding Jerry Koosman of the New York Mets, and following Jim Wynn as the second Astro.

Displeased with the result of a contest on May 15, Houston GM Spec Richardson resorted to sending his message through the scoreboard of the Astrodome, blaming umpires Augie Donatelli and Bruce Froemming for blown calls in a 4–1 loss to the Atlanta Braves. He charged the missed calls changed the outcome of the game; however, this instead resulted in a $500 fine.

Down 7–0 on May 20, the San Francisco Giants came all the way back to tie, 7–7. However, a solo home run from Jimmy Wynn gave Houston an 8–7 win, while also allowing them to take sole possession of first place.

Beginning May 30, and until June 21, Lee May put together a 21-game hitting streak to set a franchise record, punctuated by his performance during the final four days from June 17–21. On June 17, May went 3-for-5, including his 1,000th career hit.

June Lee May proceeded to tie another club record with three home runs in one game on June 21, the only three-home run game and four-run contest of his career, and Tommy Helms connected for the only grand slam of his career. Meanwhile, Ken Forsch hurled a complete game to lead a 12–2 win over the San Diego Padres. César Cedeño also homered (11) among three hits and Bob Watson scored thrice. Helms hit the grand slam in top of the fourth inning off Mike Corkins.

During the final four games of Lee's hitting streak he collected 13 RBI. Over the entirety of the steak, Lee batted .407, going 35-for-86. One curiosity emerged as Lee did not draw any bases on balls from the streak's start to finish. His record displaced Rusty Staub's 20-game streak from June 30 to July 21, 1967, and remained until surpassed by teammate César Cedeño from August 25 to September 21, 1977, when Cedeño hit in 22 contests consecutively. On June 22, 1973, the day that Lee's streak ended, he went 0-for-2 while drawing two walks.

MLB All-Star Game Center fielder César Cedeño and left fielder Bob Watson were both recognized as MLB All-Stars, representing the Astros, while the game was hosted at Royals Stadium. Cedeño was named starter at center field, his first time as starter, first Astro to start at the position, and first All-Star Game starter from the Astros since teammate Lee May at first base during the 1972 Classic. This was the second career selection for Cedeño and first for Watson. Cedeño collected a single and an RBI in three at bats while Watson was inserted as a defensive replacement in left field as the National League defeated the American League, 7–1.

August A harbinger of their fortunes against this moundsman, J. R. Richard chucked his first major league shutout on August 1, a 5–0 triumph over the Los Angeles Dodgers. Shaking a deep slump, Jimmy Wynn collected a double, single, drew a base on balls and hit a run batted in (RBI) to spearhead Houston's tallies.

On August 20, Richard stymied the Pittsburgh Pirates on a complete game two-hitter as Houston bombed to a 10-2 triumph. He took a no-hit bid into the seventh until Al Oliver singled with two outs By that point, Lee May had blasted a three-run shot in the bottom of the fourth and Bob Watson followed up in the fifth by launching a grand slam. Richard ended up with nine strikeouts and a game score of 81. Watson's grand slam was Houston's fifth of the season, tying the club record set in 1970.

September At the Astrodome on September 22, Hank Aaron hoisted a Dave Roberts offering into the left field stands during the sixth inning for his 712th career home run. The enormous outfield scoreboard commemorated Aaron's blast with, “712!” adding, “Aaron is now two away from tying mark + 3 from 715!” Aaron received one more at bat that evening, fouling out to first baseman Lee May. The Astros and Braves faced each other for four of the final six bouts of the season.

During the penultimate day of the season on September 29, Hank Aaron hammered a Jerry Reuss offering for his 40th home runs of the campaign during the fifth inning, and 713th of his career, placing Aaron just one home run away from Babe Ruth for the all-time Major League lead. The excitement crescendoed as Atlanta dropped Houston, 7–0. Darrell Evans (41) and Dusty Baker (21) also went deep, while Baker added a double (29).

On the final day of the campaign, also against Atlanta, Dave Roberts and Don Wilson collaborated to limit Aaron to three singles, placing his all-time home record quest on hiatus until the following season. Roberts (17–11) tossed the first six frames of a 5–3 Houston victory, while Wilson (2) etched a three-inning save. César Cedeño went deep (25} and purloined two more bases (56), but was also twice caught stealing (15). Doug Rader doubled (26) while collecting three safeties.

Performance overview Houston concluded the season with an record, in fourth place and trailing the division-champion Reds by 17 games. Though the Astros' record slipped from a then-franchise best by two victories and from second to fourth place, the 1972–1973 campaigns distinguished the first time in franchise annals with consecutive winning seasons. This was their third season of 81 wins or more (also 1969). Moreover, the 82 wins signified a fifth consecutive season of winning a minimum of 79 bouts, after having lost 90 or more contests in each of the first seven campaigns.

This Astros team golfed 134 home runs, which equaled the 1972 ensemble for the club record. The record maintained until the 1993, when that team hit 138. Their five grand slams tied the team record established in 1970, which they tied again in 1986, and surpassed in 1989 (six).

Cedeño proceeded to repeat the 20–50 club for the second consecutive season, with 25 home runs and 56 stolen bases, also accomplished that year by former Houston Astros teammate Joe Morgan, then a member of the Cincinnati Reds. Cedeño became the first player in major league history to repeat over consecutive seasons. In addition, Cedeño expanded on his status as the first Astro to attain 50 stolen bases for a second campaign, during a club-record span of six consecutive seasons through 1977.

Also for the first time, the Astros headlined three Gold Glove awardees. Third baseman Doug Rader captured a third sequential to extend his club record. Cedeño was recognized among outfielders for a second season, joining Rader as Astros who had won in multiple seasons. Meanwhile, Roger Metzger drew his first, also becoming the first Astro to win for the position of shortstop.
