Graveman allowed one hit, hit a batter, and struck out two over a scoreless eighth inning in Tuesday's 3-0 win over the Dodgers.
Houston, which was without closer Ryan Pressly (paternity), held a 3-0 lead entering the bottom of the eighth with the heart of the Dodgers lineup due up. Instead of holding Graveman for the ninth for a potential save, manager Dusty Baker brought him in to face the teeth of Los Angeles' lineup. He danced around a single and a hit batsman to preserve the lead before ceding the ninth inning to Ryne Stanek.
