Luis Castillo did not factor into the decision in Saturday's loss to the Cardinals, allowing four runs on eight hits across seven innings. He walked one and struck out five.
Castillo was decently effective Saturday against the division rival. After a positively brutal start to the season, he's bounced back quite well. In his last 15 starts (93 innings), Castillo has a 3.10 ERA and 97 strikeouts.
