It was a combination of heads-up defense from the Pirates and just awful baserunning by the Cardinals that allowed Pittsburgh to turn the triple play. Pirates second baseman Neil Walker skied for a line drive and threw to third base to to get the force out there, and then took a return throw back to second to get a force on the runner that had left second and had not returned.
