PITTSBURGH (AP) — Pinch-hitter Ike Davis launched a tiebreaking, three-run homer off Seth Maness in the eighth inning Tuesday night, lifting the Pittsburgh Pirates over the St. Louis Cardinals 5-2. The Pirates won after reigning NL MVP Andrew McCutchen left in the fifth inning because of discomfort in his left ribs. Recently on the disabled list because of a rib problem, the center fielder ran into the wall earlier in the game.
