MLB Power Rankings Week 3: Are Dodgers, Mets or Padres No. 1?

Three weeks into the new MLB season, there's a new No. 1 on our list.

After being a unanimous choice atop our preseason rankings, the Los Angeles Dodgers have fallen from the top spot thanks to a recent rough patch (by their standards) combined with the strong performances of other National League powerhouses.

Was it the New York Mets, San Diego Padres or San Francisco Giants who replaced the defending champions atop our Week 3 Power Rankings? Which other teams off to surprising starts surged up our list? And who took the biggest April tumbles?

Our expert panel has combined to rank every team based on a combination of what we've seen so far and what we already knew going into the 162-game marathon that is a full baseball season. We also asked ESPN MLB experts Jorge Castillo, Buster Olney and Jesse Rogers to weigh in with an observation for all 30 teams.

Week 2 | Week 1 | Preseason rankings

1. San Diego Padres

San Diego finally lost at home this week, but the Padres' advantage at Petco Park shouldn't be overlooked. It's become a more raucous environment than ever, a destination for fans who want to see a pitching staff that so far has compiled the lowest home ERA in the game and a lineup that ranks eighth in home OPS. Fernando Tatis Jr.,in particular, must like the sight lines there this year; he has an OPS over 1.100 at Petco Park. San Diego has established a home environment all smaller market teams should strive for, and the Padres are winning plenty to keep fans coming back for more.-- Rogers

2. Los Angeles Dodgers
