The home stretch of the Major League Baseball season can be exhilarating as all the races finally get settled. One of the most intriguing and competitive battles is for Rookie of the Year, in both leagues. 

There is a discrepancy between the National League and American League crop of freshman. The star power is overflowing in the senior circuit with no fewer than four players battling over the award. 

The AL crop that boasted names that fans knew—Texas’ Jurickson Profar being the most prominent—was barren for a long time but has come into its own over the last few months. 

But there is still time for the race in both leagues to change, as so often happens. As we reach the final phase of the 2013 season, here are our grades for the top rookies in each league through August 12.
