This the first time the Astros have won the American League West title since moving to the division in 2013.
"Of course! We're the greatest! We're the Astros," answered one fan when asked if he knew the Astros would win today.
Many of those at the game rushed to buy their division champions gear. The Astros team store at Minute Maid Park will be open for 24 straight hours to sell the "AL West Division Champions" shirts, hats and more.
"It was a great game! My God, we're just so happy we were here to see it," said another Astros fan.
The Astros are the fourth team to punch their ticket to the MLB postseason in 2017.
