For the third time in six weeks, a new team is crowned No. 1 in USA TODAY's MLB power rankings.
The surging Houston Astros -- who own the best record in baseball -- claim the top spot over the Washington Nationals. The Astros won three of four games against the New York Yankees in the Bronx and have opened up a 7.5 game lead in the AL West.
Meanwhile, the Chicago Cubs have lost seven out of their last nine games and have fallen to a season-low ninth in the rankings.
