What It Means:

Arrieta struck out nine on the day, but his command wasn't what we've come accustomed to during his ridiculous streak. He served up a couple doubles and a home run while walking two and hitting a batter.

It's the first time Arrieta has allowed four or more runs in a start since June 16, a stretch covering 21 straight quality starts. He gave up 1 or 0 runs in 17 of those outings. Arrieta is in line to pitch Game 1 of the next round should the Cubs finish off the Cards.
