With a stunning outburst their first time up, the St. Louis Cardinals scored 10 runs for the biggest opening inning in postseason history and dealt the Atlanta Braves another playoff heartbreak with a 13-1 rout in decisive Game 5 of the NL Division Series on Wednesday. Before many fans had reached their seats, the Cardinals were already booking their plans for the NL Championship Series, where they will face either the Los Angeles Dodgers or the Washington Nationals in a best-of-seven set beginning Friday. Those teams were meeting in their own Game 5 at Dodger Stadium.
