PITTSBURGH (AP) — Mitch Keller pitched his first career complete game and Rodolfo Castro hit a two-run homer as the Pittsburgh Pirates snapped their seven-game losing streak with a 2-0 victory over the Colorado Rockies. Keller shut out the Rockies on four hits while striking out eight and walking one in a game that took just 1 hour, 55 minutes. The fifth-year veteran had never pitched into the eighth inning before. Castro’s homer off Kyle Freeland in the seventh carried into the bullpens in center field and broke a scoreless tie.
