In his first back game with the Astros after dealing with a personal matter, Gregerson allowed two hits and struck out a batter during a scoreless ninth inning Wednesday to earn his eighth save of the season. San Francisco kept things interesting in the ninth innings Wednesday, as Brandon Crawford led off the inning with a double, but was thrown out at third following Nori Aoki's fielder's choice. Gregerson struck out Matt Duffy for the second out of the inning, but Angel Pagan singled to center to put runners at the corners for Buster Posey. Gregerson induced a weak grounder to end the game, however, to move into seventh place among AL relievers with eight saves.
