Probably not. The biggest problem baseball has is the length of the season. Between the general expectation of every team losing 1/3 of the games, and how much the personnel of team can change over the season, higher ranked teams can easily be there because of May and June performance and not be nearly as good as the record says by October. Meanwhile a team like the D-Backs can basically reinvent themselves at the trade deadline and be a significantly better team by the end of September than their record says.
Actually Arizona was 16 games over .500 in June, then collapsed in July and August, and at one point were two games under .500. Only the Cubs epic collapse got them in.
