PITTSBURGH -- Jordy Mercer singled home Gregory Polanco from second base with one out in the 11th inning to lift the Pittsburgh Pirates to a 6-5 win over the St. Louis Cardinals on Tuesday night.
Polanco, who agreed to a $35 million, five-year contract earlier in the day, drew a walk from Seth Maness (0-1) with one out and made it to second on Josh Harrison's infield single. Mercer slapped a single to right for his fourth career game-ending hit.
Kyle Lobstein (1-0) pitched two innings of relief for the win.
