Spencer Arrighetti tossed a gem as the Houston Astros beat the Seattle Mariners 4-0 at T-Mobile Park. The Astros' starting pitcher threw six innings, did not allow a run and struck out eight. Alex Bregman and Victor Caratini hit home runs in the victory. The Astros snapped a three-game losing streak to improve to 25-and-32. They return home to host the Minnesota Twins tonight. Right-hander Ronel Blanco will start opposite Minnesota righty Pablo Lopez.
