Ramirez (2-2) allowed three runs on six hits and a walk while striking out nine over 5.1 innings during Wednesday's 5-1 loss to the Astros.
He threw 53 of his career-high 83 pitches for strikes, while the nine strikeouts were also a personal best. The 28-year-old will take the hill again Tuesday at home against the A's, assuming Alex Meyer doesn't bump Ramirez to the bullpen right away upon his return.
