Arizona Diamondbacks rookie starting pitcher Robbie Ray hasn’t earned a win since July 7.

Most rookies will take all the help they can get, but the D-backs batting order hasn’t provided Ray with much help this season.

His 2.76 average run support is the lowest of all rookie major league pitchers with over 80 innings pitched this year.

Perhaps it’s bad luck, a regression to the mean, or simply a combination of the two.  No matter how you slice it though, there’s no doubt that Ray has endured a roller coaster rookie campaign.

Below, we take a look at Ray’s stats, by the numbers.


In August, Arizona averaged 4.67 runs per game.


However, in August, Ray received even less help with a minuscule average run support of 1.67 over the six games he started.


Ray’s ERA following his win on July 7 was an impressive 2.16 through eight starts.


Since that win, Ray’s ERA has been gradually rising. It rose above 3.00 for the first time on August 2 and has only ballooned since. Now through 17 starts, it sits at 3.72, a far cry from the 2.16 ERA he took into the All-Star break.


In August, Ray saw his toughest month yet with the Diamondbacks. His ERA was 6.00 over six starts where he averaged just five innings pitched.


Ray’s pitch count in August average 95.5 pitches per appearance. While that number isn’t astounding, only averaging five innings per appearance on 95.5 pitches is far from ideal.


When your team isn’t scoring any runs and opposing batters are hitting .307 off of you in August, the perfect storm is brewing to prolong your win drought. The good news for Ray? His season average is about 50 points lower at .258.
