The 2007 Houston Astros season was the 46th season in team history. After finishing 1½ games behind for the National League Central to the World Series champion St. Louis Cardinals, the Astros elected to a select amount of subtractions and additions to compete. Jeff Bagwell (who had shoulder problems that had him play his last game in 2005) retired after the Astros declined to pick up his $18 million club option for 2007, instead buying it out for $7 million. Pitchers Andy Pettitte and Roger Clemens both filed for free agency on November 6 and re-joined the New York Yankees. To make up for losing those key players, they signed pitcher Woody Williams, and traded with the Colorado Rockies for Jason Jennings and Miguel Asencio. The largest offseason move the Astros made was signing outfielder Carlos Lee to a 6-year contract worth $100 million, the most in franchise history. On June 28, second baseman Craig Biggio achieved his 3,000th career hit. The club officially retired Bagwell's jersey number 5 on August 26. On September 30, Biggio played his last game as a major league player, having announced his retirement on July 24.

Season summary

On April 28, the Astros purchased the contract of Hunter Pence, the organization's top prospect from Triple-A affiliate, and made his debut that night where he got his first career hit and run scored. By May 2007, the Astros had suffered one of their worst losing streaks since the 1995 season with 10 losses in a row, losing 4–3 to the Cincinnati Reds on May 30. The Astros were just one loss shy of tying their worst skid in franchise history, before snapping that streak the next day, also against the Reds. On June 12, the Astros beat the Oakland Athletics for the first time in team history. Longtime Astros second baseman Craig Biggio recorded his 3,000th career hit in the seventh inning against the Colorado Rockies on June 28, becoming the 27th player in MLB history to do so. Jeff Bagwell, who played first base for the Astros alongside Biggio for 15 seasons, was in the dugout and emerged to congratulate him. The Astros fans, who had momentarily quieted after cheering Biggio for his achievement, erupted into cheers again the moment Biggio dragged Bagwell onto the playing field and to the first base line. "The thing with Baggy is that he and I worked so hard here for this city and for this organization," Biggio remarked. "We made so many sacrifices as far as playing the game and giving your body to a city, a team." Together, they bowed to the crowd as Bagwell raised Biggio's arm and returned to the dugout. In the bottom of the 11th inning of the same game, Carlos Lee hit a towering walk-off grand slam to win the game for the Astros. On July 24, Biggio announced that he would be retiring at the end of the 2007 season, his 20th season with the club (and a franchise record). He hit a grand slam in that night's game which broke a 3–3 tie and led to an Astros win. On July 28, the Astros traded RHP Dan Wheeler to Tampa Bay for right-handed slugger 3B Ty Wigginton and cash considerations. He is now signed through 2009. On July 29, long time and former All-Star third baseman Morgan Ensberg was designated for assignment to make room for newly acquired Wigginton. On August 26, the club officially retired Bagwell's jersey number 5 prior to the start of the game against the Pittsburgh Pirates. He was the eighth player in Astros history to have his number retired. Three first bases were used in the game, each embossed with a commemorative insignia that said, "No. 5, Jeff Bagwell jersey retirement, Aug. 26, 2007." One was given to Bagwell and the other two were auctioned to raise funds on behalf of the Astros in Action Foundation. On August 27, manager Phil Garner and General Manager Tim Purpura were relieved of their duties. Cecil Cooper and Tal Smith were named as temporary replacements, respectively. On September 17, in a 6–0 loss to the Brewers the Astros were officially eliminated from the 2007 playoffs. On September 20, Ed Wade was named as the new General Manager of the Astros. He made his first move as GM by trading Jason Lane to the Padres on September 24. On September 30, Craig Biggio retired, ending a 20-year career with the Astros.
