A 1-game playoff is just very un-baseball like.
I understand the desire to put more emphasis on winning their division (though lets be honest, the 2nd wildcard was designed to try and increase interest), but it seems like manufactured excitement IMO.
Instead of the added wildcard and "1-game playoff", they should have instead given the team with the best record in the league all 5 potential games at home in the ALDS vs the wildcard. It rewards teams to strive for the best record up until the very last day with 5 home games instead of 3, and it punishes the playoff team that didn't win their division by forcing them to play on the road the entire series -- but you still keep the very heard of what baseball is about... a "team" that includes 4-5 members of a pitching rotation getting a shot.
