5) CRAIG BIGGIO'S 3000th HIT

The Astros had a terrific run with Craig Biggio and Jeff Bagwell leading the way, but by 2007, the run was coming to an end. They never quite got over the top, but in the last great moment of the era, Biggio would get his 3000th hit on June 28 against the Colorado Rockies. It would be his third hit of a five hit night and would all but guarantee his spot in the Hall of Fame.

4) MIKE SCOTT'S CLINCHING NO HITTER 

On Sept. 25, 1986, Mike Scott took the mound against the San Francisco Giants with a chance to clinch the NL West and earn the team's second all-time playoff appearance. Back then, there were two divisions in each league, and the winners of each met in the NLCS. Scott would punch the ticket in amazing fashion, striking out 13 Giants and pitching a no-hitter. It was the only time a division was clinched with a no-hit performance and it topped this list for many years. The Astros would go on to lose a classic series against the Mets, but the Scott moment would live in Houston lore forever.

3) ALTUVE'S BLAST

Tied in the ninth, Jose Altuve hit a walk-off home run off of Aroldis Chapman to send the Astros to the World Series for the third time in history and second time in three years.

2) ALEX BREGMAN'S WALK-OFF IN GAME 5 OF THE 2017 SERIES

It did not win a title - yet - but it did put the Astros up 3-2 in the Series, which they would go on to win in seven games. Alex Bregman's hit drove in Derek Fisher in the bottom of the 10th inning to give the Astros a 13-12 win in one of the greatest World Series games ever played. Without it, the Astros do not win their first World Series.

1) ROCKETS WIN GAME 7 AGAINST THE KNICKS FOR FIRST TITLE

The 1993-94 Hakeem Olajuwon led Rockets were on the cusp of their first ever NBA title, and the first major sports championship in the city's history. Olajuwon came up big in Game 7 with 25 points, 10 rebounds, 7 assists and 3 blocks as the Rockets held on for the 90-84 win as the Knicks' John Starks shot 2 for 18. As the clock ticked down to zero, the city had its first ever title in a major sport, after decades of incompetence.
