The Astros put up two runs in the top of the fifth during a 3-1 win over the San Francisco Giants. The game was tied at one entering the frame before Alex Bregman laced a two-run go-ahead single. Ronel Blanco earned his sixth win after striking out eight and allowing just one run on three hits over six innings, while Ryan Pressly picked up his second save. The Astros have won three of five to sit at 31-and-37. They visit the Giants again this afternoon. Left-hander Framber Valdez will start opposite San Francisco righty Logan Webb.
