Welcome to the Rotoworld MLB Power Rankings, a weekly feature that will run every Tuesday through the end of the 2019 regular season. Winning percentage isn't everything when it comes to crafting these rankings, but the Yankees do have the best record in baseball and they get top billing here after relatively mediocre recent stretches for the Dodgers and Astros. In a potential National League Championship Series preview, the Dodgers dropped two of three to the Braves this past weekend at Atlanta's SunTrust Park.
