St. Louis, MO (SportsNetwork.com) - Gaby Sanchez delivered a two-run double to highlight a breakout fourth inning for Pittsburgh, and the Pirates overcame an early exit from Francisco Liriano to produce a 6-1 victory over the St. Louis Cardinals and end a four-game skid.

Liriano tossed a pair of scoreless frames before being removed due to flu-like symptoms, but Stolmy Pimentel and Jared Hughes combined for four innings of one-run ball and Pittsburgh's struggling offense finally got on track in the fourth, scoring four times on four hits that also included RBI singles from Andrew McCutchen and Jose Tabata.

Tony Sanchez added a two-run single later on for a Pirates team that had mustered just four runs total during the losing streak and had a mere four hits in dropping Friday's opener of this three-game set by a 1-0 count.

Pimentel (2-0) received the win after permitting one run over 2 2/3 innings in relief of Liriano.

St. Louis starter Tyler Lyons (0-2) retired nine straight hitters to begin the contest and concluded his six-inning stint with eight consecutive outs, but was hit hard during a six-batter stretch in the fourth that was the difference in the game.
