Cubs have won 19 of Arrieta's last 20 starts - 18 of those 19 wins by 2+ runs. Just an incredible streak

Everything with the Cubs this year is better than ever. The offense is incredibly prolific, the defense is #1 in the league in efficiency, the bullpen is #1 in ERA/Whip

I wouldn't be surprised if Arrieta goes something like 28-2 this year
