PITTSBURGH — As Paul Goldschmidt has workshopped his swing in the batting cage and convened with video for any pointers it might offer about how to unlock his production, he has been searching for a constant that could lead to consistency.
Less than a week after his three-run homer capsized Pittsburgh at Busch Stadium, Goldschmidt launched a grand slam in extra innings to send the Cardinals to a 6-5 victory at PNC Park. The grand slam pushed the Cardinals ahead by four runs heading into the bottom of the 10th, and they needed every one of those runs to weather Pittsburgh’s last-gasp rally against lefty Chasen Shreve and closer Carlos Martinez.
