Markos Moulitsas ("kos" of Daily Kos) dealt some sage advice for baseball fans on Monday to mark the 2009 Opening Day of baseball.

He tweeted:
Happy Baseball Day! And as every year, believe it or not, there are more teams than the Red Sox and Yankees playing.

Check out today's matchups here. While the Yankees are set to play the Orioles (where Vice President Biden will throw the opening pitch), the Rays-Red Sox opener has been postponed due to weather.
