MLB power rankings: Astros head into second half of season No. 1

The Houston Astros start the second-half of the season with the No. 1 spot in Paste BN Sports' MLB power rankings.
But don't look back, their reign of nine straight weeks at the top spot is being challenged by the re-hot Los Angeles Dodgers.
The Dodgers have won 26 of their last 30 games and have a one game advantage in the win column over the Astros. The Dodgers’ plus-163 run differential is also the best in National League history for a team heading into the All-Star break.
