Walker allowed four hits and two walks while striking out three across 7.1 scoreless innings Wednesday against the Astros. He did not factor into the decision.
Walker induced 12 groundball outs to keep Houston's bats in check and deliver his third scoreless outing of at least five innings on the season. He's been on a particularly strong run of late, turning in four consecutive quality starts, during which he's allowed only five earned runs across 26 innings. On the campaign, Walker owns a 2.72 ERA with a 52:21 K:BB across 72.2 frames.
