Cubs starter Jake Arrieta finished out the regular season with six shutout innings against the Brewers, extending his scoreless innings streak to 22. He scattered two hits while walking none and striking out seven, leaving with a 5-0 lead. It’s his 20th consecutive quality start.

As STATS notes on Twitter, Arrieta’s 0.75 post-All-Star break ERA is an MLB record. His 1.77 overall ERA is the lowest by a Cubs starter since 1919, the Dead Ball Era. Along with the 1.77 ERA, Arrieta is likely to push his major league-leading wins total to 22 and he has a 236/48 K/BB ratio in 229 innings.

Zack Greinke, Arrieta’s competitor for the NL Cy Young Award, starts Saturday night for the Dodgers. Greinke is 18-3 with a major league-best 1.68 ERA and a 192/39 K/BB ratio over 214 2/3 innings.
