Valuing the Major League Baseball staffs from highest grade to lowest, complete with separate rotation and bullpen grades:
Overall grade: A
Rotation: The New York Mets have the best starting rotation in baseball, and it'll get even better when Zack Wheeler returns from Tommy John surgery around midseason. This unit carries the overall staff to the highest grade.
Bullpen: The Mets have an impact closer in Jeurys Familia, and Addison Reed should be solid in the eighth inning. Antonio Bastardo had a poor spring but should be a solid contributor from the left-handed side, along with Sean Gilmartin. Veteran Jim Henderson surprised some by making the team this spring, 25-year-old Hansel Robles should be better with a year of development, and Jerry Blevins should prove useful.
Overall grade: A-
Rotation: The Cleveland Indians have arguably the best rotation in the American League. It led the majors in strikeouts from their starting pitchers, and the unit remains intact for this season. In fact, as scary as it sounds, we might not have even seen the ceiling for power arms Carlos Carrasco and Danny Salazar. The Indians have one of the league's weakest offenses, but this group will keep the team in a lot of games.
