If the postseason started today, five teams in the top half of major-league payrolls at the beginning of the year would qualify for the playoffs: the Boston Red Sox, Chicago Cubs, Los Angeles Dodgers, New York Yankees, and Washington Nationals*. That means that five teams in the bottom half of Opening Day payrolls would make the playoffs as well — in this case, the Arizona Diamondbacks, Cleveland Indians, Colorado Rockies, Houston Astros, and Minnesota Twins.
*Numbers current as of yesterday.
Presenting the standings in this way might give one the impression that we remain in an age of great baseball parity. An age in which the Kansas City Royals can win the World Series, Cleveland can get there, too, and teams like the Pittsburgh Pirates can sustain multiple years of playoff contention.
That isn’t quite the case, however.
Of the clubs that feature top-six payrolls this season, three have playoff chances of at least 96% (Dodgers, Red Sox, Cubs). A fourth, the Yankees, aren’t too far behind. If the Twins can’t hold on to a playoff spot and are overtaken by anyone but the Rays, the only team in the bottom 12 of payrolls this season to make the playoffs will be the Arizona Diamondbacks, and even their spot isn’t a guarantee. Money buys players, and those players rack up wins for their ball clubs. Last season, at around this time, I took a look at the relationship between payroll and wins, and noted that the relationship was one of the strongest we had seen in a while. This is what it looked like at the end of last season.

Last season saw one of the strongest relationships between payroll and wins to exist in several decades. Here’s how the relationship has developed since 1990, with help from data courtesy Brian MacPherson.

In the early 90s, Major League Baseball was coming off an era of collusion and lack of expansion. That, combined with a new influx of talent from outside the United States, meant that simply paying for major-league talent wasn’t the only solution to winning major-league games. (To track back further, read Dave Studeman’s piece in Hardball Times on the subject.)
