2013 Houston Astros season

The 2013 Houston Astros season was the team's first year as a member of the American League, with them switching from the National League Central to the American League West. This was also their 52nd season as an MLB franchise, their 49th as the Astros, and their 14th at Minute Maid Park.

The Astros continued their exceptionally poor records from 2011 and 2012, winning only 51 games, the fewest by any Major League Baseball team since the 2004 Arizona Diamondbacks who finished with an identical record. Perhaps the lowest point of the season came when the Astros finished with a 15-game losing streak. Other lowlights included winning only 12 series (2 of which were sweeps, none outside of the AL West), getting swept 18 times, finishing 45 games out of first place, winning just 2 games against the rival Texas Rangers and 4 games against the Oakland Athletics, getting shut out 14 times (twice in a row against the Rangers and the Rays), and yielding 10 runs or more in 17 games.

Television coverage
Astros games were televised on the Comcast SportsNet Houston network in 2013. The network broadcasts to about 40% of the households in the Houston area. Writer J. J. Cooper said that a game in September received a 0.0 rating, as "the Nielsen company could not statistically prove that anyone in the Houston market actually watched the game."
