Walker (3-1) earned the win Wednesday versus the Orioles after allowing one run on four hits with four strikeouts and three walks over seven innings.
The 28-year-old blanked Baltimore through six frames, but the Orioles scratched across a run on a walk, a single and a groundout during the seventh inning. Walker has won three of his past four starts and given up only five earned runs across 27 innings during that stretch.
