NOTES: The start of the game was delayed 1 hour, 59 minutes by rain. ... The Cardinals scratched third baseman David Freese from the starting lineup for irritation on a finger of his right hand. He got hurt during an at-bat in Friday's home opener against the Cubs. He is as day to day. ... Before the game, the Cardinals had a pregame ceremony to present World Series rings to players and coaches. ... In Sunday's series finale, both teams will mark the 65th anniversary of when Jackie Robinson broke the color barrier. All players will wear No. 42 as part of a tribute to Robinson's legacy.
