After this weekend's Cardinals sweep of the Cubs, many fans have been wondering if this really is as much of a rivalry as the media makes it out to be. The perception seems to be that the fans are not as into it as they are other rivalries (perhaps White Sox, Royals), and that it has been a mostly one-sided match-up in recent years. While it is difficult to measure the first claim, we can examine the second. The table below shows the last 20 years of Cubs-Cardinals match-ups, including the head-to-head record for that year and each team’s overall winning percentage at the end of the season.
