Today was a crucial day in the MLB Heavyweight Championship, as the Washington Nationals defeated the Texas Rangers, 8-1.

Because of a quirk in the scheduling, this game may have been the last interleague championship bout of the year. There is one more weekend of interleague play remaining. However, since the NL has two more teams than the AL, two NL teams won't play interleague games next weekend: the Pittsburgh Pirates and the St. Louis Cardinals.

The current champs, the Washington Nationals, play the Pirates Monday through Wednesday. If the Pirates beat the Nationals on Wednesday, then the heavyweight crown will remain in the National League for the rest of the season.

American League teams need the Pirates' Josh Fogg to beat the Nationals' John Patterson to have a chance at any more title bouts this season.

If that happens, and the Nationals win on Wednesday, then the AL will have one more chance on Sunday to keep the crown in the AL, when the Nationals host the Toronto Blue Jays.
