The Los Angeles Dodgers' Corey Seager and the Detroit Tigers' Michael Fulmer were the leading rookies back on my June breakdown of ranking the class with shortstops Trevor Story of the Colorado Rockies and Aledmys Diaz of the St. Louis Cardinals not far behind.

Since then a lot has changed. A trio of outfielders have jumped onto the board. In addition, a young class of rookie starters have made an impact since and two rookie relievers have quickly become some of the game's best.

The 2016 class did not disappoint but because of injuries to Story and Diaz, it looks as though the frontrunners -- Seager and Fulmer -- will hold on to their lead for National League and American League Rookie of the Year Awards despite stiff competition.

Here is the breakdown of the best of the class as of today.
