St. Louis: A determined Chicago Cubs scratched out an unusual five-run rally in the second inning that carried them to a 6-3 victory over the top-seeded Cardinals that evened the best-of-five series 1-1 on Saturday. Two errors led to the five unearned runs, with Cubs manager Joe Maddon putting pressure on the Cards with back-to-back squeeze bunts that scored runners from third each time. “Joe has a good understanding about what’s going on in the game and what needs to be done,” said Addison Russell, who laid down the second squeeze bunt after pitcher Kyle Hendricks succeeded with the first, which resulted in a wild throw.
