ST. LOUIS (AP) — Rosters turn over so quickly these days, the St. Louis Cardinals used only six players from their 2011 World Series roster in this year’s NL championship series. The NL champions got contributions from 20 rookies this season, many in starring roles on a team that led the NL with 97 wins and then reached the World Series for the second time in three years.

Lance Lynn is the only pitcher left from two years ago, joined against the Dodgers by position players Matt Carpenter, Daniel Descalso, David Freese, Matt Holliday and Jon Jay. Allen Craig, sidelined by a foot injury since early September, is expected to join them in the Series.

When the Cardinals were swept by Boston in the 2004 Series, Michael Wacha and Trevor Rosenthal were in middle school. St. Louis worked out Sunday after a day off to savor the NL pennant. They leave for Boston on Tuesday, and just a handful have firsthand experience of the ill-fated 105-win team that got swept by the Red Sox.
