Cardinals continue postseason push versus Pirates

Looking to buy their starting pitchers some rest during the final three weeks of the season, the St. Louis Cardinals have opted for a six-man rotation on this turn through it. The sixth man goes Wednesday against the Pittsburgh Pirates in Busch Stadium, where St. Louis tries for a series sweep and to solidify its postseason position. Rookie Daniel Poncedeleon (0-1, 2.67 ERA) gets the call for the Cardinals, who moved three games ahead of the Los Angeles Dodgers for the National League's second wild card spot Tuesday night.
