For the second-consecutive season, the Houston Astros are American League West Division champions.

The Astros, who went into Tuesday with a magic number of two, took care of their part, defeating the Toronto Blue Jays, 4-1, capturing their 100th victory of the year in the process.

Houston was paced by Alex Bregman, who crushed a two-run home run in the top half of the first inning, his 31st of the season, to get them off to a quick start:

Then, the Astros got a little help from the Seattle Mariners, who got a walk-off home run by Chris Hermann in the bottom half of the 11th inning to defeat the Oakland A's, 10-8.

Now with 100 triumphs, the Astros became the first World Series winner to win 100 games the very next season in 28 years, and only the fifth team in the last 50 years.
