Four startling stats regarding Greinke’s poor start

Zack Greinke’s 2016 season has not gotten off to a great start. In fact, it hasn’t even gotten off to an okay start. The Diamondbacks’ $206.5 million-man allowed four runs to the Cubs on Saturday after allowing seven to the Rockies earlier in the week.
Obviously, it’s still early. Things can change very easily. But it’s already looking like the 1.66 ERA Zack Greinke put up last season will be impossible to replicate.
Greinke has now allowed 11 earned runs this season. He didn’t allow his 11th earned run of 2015 until May 27. But that’s not the only stat contrasting Greinke’s last two seasons.
Ace of MLB Stats (@theaceofspaeder) is one of the best follows on Twitter. He tweets stats that you didn’t even know existed on the reg. He took some time on Saturday night to address Zack Greinke’s two poor outings:
#Dbacks Zack Greinke has already allowed 26.8% of his 2015 earned run total this season.

Yes, that is over a quarter in a week.
In order to have the same ERA as last season with the same number of innings pitched Greinke will have to have a 1.28 ERA from here on.

#Dbacks Zack Greinke has allowed more earned runs this month than he did in ANY month last season.

Obviously, asking Greinke to repeat the numbers he put up last season will be a tall task. A 19-3 record and a 1.66 ERA are statistics that show up only a few times in a generation. But two starts into the season, they already look mathematically impossible to repeat.
