Power Rankings: Preseason favorite Red Sox return to No. 1

Week:

ESPN.com

The Boston Red Sox were dubbed the No. 1 team in our preseason Power Rankings. Now they're back, courtesy of a 10-game winning streak that includes a weekend sweep of the rival Yankees.

The Red Sox jumped seven spots in the rankings and barely held off the Los Angeles Dodgers, who remain at No. 2 for the second straight week, and the No. 3 Toronto Blue Jays, who own baseball's best record at 14-6 and lead the Red Sox by a game in the AL East.

Meanwhile, last week's No. 1 team, the Florida Marlins, fell back to Earth. After losing six straight games, the Marlins dropped four spots to No. 5.

The team comments below were written by one of our panelists, Enrique Rojas of ESPNdeportes.com. Meanwhile, you can rank the teams yourself.
