I don't like the expanded playoffs. HOWEVER, this team, over a full 162 games, may very well have made the playoffs even under the old, better, system. At the very least, they would have been in the race in September still, and baseball is ridiculously impossible to predict game to game, so we can't really know.
I'm glad they made it, and I'm glad they made it in with a > .500 record, it's going to be the sub .500 teams making it in every year that will piss me off. "We won nearly half our games! Playoffs baby!" is not something I would consider a victory.
