PITTSBURGH (AP) — Nick Gonzales hit a go-ahead RBI single in the eighth inning after Mitch Keller allowed one run in the first seven, and the Pittsburgh Pirates won for the seventh time in eight games, 2-1 over the St. Louis Cardinals. Bryan Reynolds led off the eighth with a single to left before advancing to second on a wild pitch. With one out, Gonzales sneaked a slow dribbler off John King through the right side of the infield. Keller gave up six hits in seven innings, striking out three and walking two. Aroldis Chapman pitched a perfect eighth for the win in this matchup of NL wild card contenders.
