Alex Cora agrees with Major League Baseball's new rules but had one issue with the enlarged bases.

"The bases, they're the bases," the Boston Red Sox manager said. "Wait 'til you see them -- they look like a pizza box, to be honest with you."

Baseball has adopted a series of new rules that will be implemented this season, including increasing the size of the bases from 15 square inches to 18 square inches.

The enlarged bases are primarily intended to promote safety -- first basemen are less likely to get stepped on -- but also are expected to lead to an increase in stolen base attempts because the basepaths have been shortened by 4 inches.
