What's the deal with all the extra innings?

When the Chicago White Sox scored two runs off Jordan Walden to send Wednesday's game into extra innings, it had a familiar feel. It was the Angels' ninth extra-inning game this season in their first 38 games.

That's a "pace" for 38 extra-inning games, if such terminology has any meaning for such a fluky set of circumstances. The MLB record for extra inning games in a season is 31, set by the Boston Red Sox in 1943, according to Steve Glasser of ESPN's Stats and Info department.

The last team to play so many extra-inning games so soon in the season was the 2008 Milwaukee Brewers. They finished with 20.
