Quintana allowed four runs on six hits while striking out five batters through 4.2 innings during Friday's win over Cincinnati. He didn't factor into the decision.
Quintana posted a 1.63 ERA, 0.90 WHIP and 10.1 K/9 through his previous four September starts, so while he'll finish the regular season on a bit of a downer, the lefty heads into the postseason on a high overall. However, the real test is still ahead, as the Cubs will be depending on Quintana to be at his best against other high-end hurlers in the playoffs.
