Fernandez tops rookie rankings again

As we head into the final weeks of the season, the one thing that really stands out is how much stronger the National League rookie class is than that of the American League and how deep this rookie class is in starting pitching -- with six hurlers making my top 10.

Of course, some rookies have dominated so thoroughly that they’ve either sat in the top position for months or have done so at one point. However, some rookies are surging with at-bats and innings under their belts. Here’s how my monthly rookie rankings stacked up through August.

1. Jose Fernandez | RHP | Miami Marlins

In August, Fernandez was named NL Rookie of the Month for the second consecutive month, becoming the first pitcher to win the award twice in a single season since Atlanta Braves closer Craig Kimbrel did it in 2011.

Fernandez made six starts in the month, finishing with a 3-1 record and an impressive 1.15 ERA and limiting opposing batters to a .158 batting average. In 15 of his past 16 starts, he hasn't allowed more than two runs and is averaging 9.8 strikeouts per nine innings on the season with a WHIP below 1.00. His mid-to-upper 90s fastball and devastating secondary pitches have not only cemented his spot as the season’s best rookie but as one of the game’s best pitchers.
