The lefty had six strikeouts over seven shutout innings as the Pirates stopped a four-game losing streak with a 5-0 victory over the Oakland A's on Wednesday night.

Severe storms in western Pennsylvania caused a rain delay of almost three hours while dark clouds hung over PNC Park. The game didn't get started until nearly 10 p.m., and it ended shortly before 1 a.m. Thursday.

Pedro Alvarez continued his hot hitting for Pittsburgh, going 2-for-4 with a two-run double that raised his RBI total to 60.

Jose Tabata, Russell Martin and Andrew McCutchen chipped in with an RBI each to support Liriano (9-3), who allowed four hits and just one walk.
