Jake Arrieta has the second-best 19-game ERA since 1914

Cubs pitcher Jake Arrieta has been really good in his past 19 starts. Historic levels of good.

According to Baseball Reference, since Arrieta’s June 16 start, the right-hander has posted a 0.98 ERA.

That’s the second-best ERA over a 19-game stretch since 1914, behind only Bob Gibson, who posted a 0.68 ERA over a 19-game stretch in 1968.

Gibson was, without a doubt, dominant, as he set a modern ERA record of 1.12 that season. But, when considering that the entire American League batted a combined .231 in 1968, Arrieta’s numbers seem just as impressive.

The Cubs pitcher is 15-1 in the 19 starts with 14 runs allowed in 141 innings of work.
