The Baltimore Orioles were swept.
It was the first time in the history of the franchise. Only 7 teams have never been swept in the playoffs, and that's mostly because they aren't in the playoffs that much. Those 7 are the Blue Jays, Rays, and Mariners in the American League, and the Mets, Nationals, Marlins and Brewers in the National League. I should note that four those those seven have never won the World Series, and with the exception of the 2000 Mariners (they swept the White Sox in the 2000 Division Series), none have ever swept anyone.
Most have multiple instances of sweeping and getting swept.
That basically means that the playoff system is pretty good, as there are few blowouts. Of 119 World Series to date, only 18 have been sweeps: Eight by the Yankees (6 of those were more than 60 years ago), two each by the Red Sox, Reds and Giants, and one each by the Braves, Dodgers, Orioles and A's. Of those eight teams, 6 have also been swept in the World Series. The Red Sox and Orioles are the only exceptions. And they're my two favorite teams.
It's the Royals against the Giants or Cardinals. In the NLCS I'll root for the Giants because of Buster Posey, former All-Star catcher for the Yarmouth-Dennis Red Sox of the Cape Cod League. But in the World Series, it has to be the Royals so that only the Red Sox have three championships in this century. Makes sense to me.
