MLB power rankings: Defending World Series champion Astros open season ranked No. 1

The Houston Astros have a tall task ahead of them.

No team has won back-to-back World Series titles since the New York Yankees in 1998-2000. Then again, no American League team has reached the League Championship Series six consecutive years like the Astros, either.

So, not surprisingly, the Astros open the 2023 major league season as the preseason No. 1 team in USA TODAY Sports' MLB power rankings.

The San Diego Padres, who rank No. 3, spent the offseason spending cash. They have an expected payroll near $250 million after extending Manny Machado's contract ($300 million) and signing free agent Xander Bogaerts ($280 million). The expectations are to win in Southern California.

The first pitch is Thursday with a long, grueling season to follow.

Here are USA TODAY Sports' power rankings heading into the season.
