We have ranked the top 10 rotations and the the top 10 bullpens, and now it's time for Part 3 of our series ranking team units: the top 10 infields -- for overall play, not just defense or offense -- based on the input from MLB evaluators.

1. Chicago Cubs

Cubs first baseman Anthony Rizzo finished 10th in National League MVP voting in 2014 and fourth last year. Third baseman Kris Bryant was the NL Rookie of the Year, after reaching base 230 times in his first 151 big league games. Addison Russell and the Cubs thrived after he took over at shortstop and established a more consistent defensive presence at the most important infield position.

And during the winter the Cubs added the cherry on top of what appears to be the best and most well-rounded infield in the majors, signing Ben Zobrist to play second base. His defensive metrics dipped last season, but keep in mind that he had midseason knee surgery, and Zobrist continues to be a very strong offensive player among middle infielders; he had a .359 on-base percentage and .809 OPS. He also has proved adept against lefties -- he hit .329 against them in '15 -- which could be a skill more valued in the Cubs lineup as opposing managers attack Kyle Schwarber and Rizzo with lefties.

Here's another thing about this group: The players are all similar in personality and professionalism, and even if they weren't the best group of infielders -- which they are -- they would have a great experience playing together.
