McCullers (9-4) was tagged with the loss Sunday against the Angels after allowing two runs on six hits and a walk while fanning eight across 5.2 innings.
McCullers ended just one out away from recording a quality start, but the strong outing wasn't enough to lift the Astros to a win over the Angels in the series finale. McCullers has been particularly good when it comes to striking out batters, as he has fanned at least eight in seven of his last eight outings. The veteran owns a 3.22 ERA on the season across 113.2 innings.
