Probably but perhaps not at the end of the season. A reverse example is the AL Central. A team with a .500 record leads the Division. The disparity as you probably know is due to the scheduling. Just a few years ago each team played a team in the same division 19 times. Now it's 11. That means that each team in a 5-team division plays just 44 games within their division. 44 out of 162, a mere 34%. But the Division winner is not predicated on 44 games, rather 162, Do you smell a fault? With this scheme a team can win a division being, say, five games over .500 which brings up the question, are they even qualified for the playoffs? No, they shouldn't because there will no doubt be teams in other Divisions who have better records but will not qualify. If the season were to end today, the Central Division winner with a record 38-38 will go ot the playoffs, while the Orioles, Yankees, Blue Jays, and Red Sox get fucked.
