1906 Chicago Cubs. 116-36. They've tied the AL mark, but not the MLB mark yet. Still a few games to go.

I thought the Cubs had 120 wins, but I must have mis-remembered that as finishing 20 games ahead of the Giants.

Still, as impressive as the Mariners fared in this now-highpaying-sport, with a damn lowpaying team, the Cubs' 152-game record remains better.
