Major League Baseball teams have improved racial diversity in hiring senior administrators, but the employment of women is still lagging.

That's according to the annual report by Richard Lapchick's Institute for Diversity and Ethics in Sports at the University of Central Florida.

Racial diversity among senior team administrators improved to nearly 20 percent from 17 percent.

MLB's central offices have 31 percent people of color. The sport's overall score equaled its top mark in 2010, and racial hiring received an A grade for the fifth straight year. Gender hiring remained a C+.
