The topic of parity came up Thursday on "Baseball Tonight," and Rick Sutcliffe mentioned how the sport has changed over the last decade, in the wake of the steroid era.
Many, many pitchers have used performance-enhancing drugs, for sure, but the simple fact is that since Major League Baseball adopted testing, offensive numbers have been in sharp decline. There is also less opportunity for hitters -- and, by extension, teams -- to distinguish themselves. The potential variance between clubs has declined.
The same sort of thing happened in the latter half of the 1960s, as pitching increasingly dominated. In 1968, the Year of the Pitcher, none of the 10 National League teams won less than 72 games, and only one team won more than 88 -- the St. Louis Cardinals, who finished 97-65. Every team averaged between 2.9 runs per game and 4.2 runs per game.
There was a greater range of performance in the American League in 1968, with the Tigers posting a record of 103-59. But every team averaged between 2.9 and 4.1 runs per game that year, and in the season before, 1967, the AL saw an incredible race because of the parity in another season of few runs. Boston led the AL with 92 wins, while Detroit and Minnesota won 91, the White Sox 89, the Angels 84. The Kansas City Athletics were the only AL team to win fewer than 72 games.
Baseball altered the rules in response to the decline in offense, lowering the mound, and if Major League Baseball wants something other than general parity and games with fewer runs, it will probably have to revisit this -- perhaps lowering the mound again, or changing the composition of the ball.
