With just about six weeks remaining in the season, 17 teams are either leading their division or are within five games of the division or Wild Card lead. That covers teams that are running away with their divisions (Cubs, Nationals), teams that have come on strong in the second half (Mariners, Tigers) and even some teams that tore it down at the Trade Deadline and are technically rebuilding — specifically, the Yankees, who are a mere 4 1/2 back in the AL Wild Card race.
