The latest post on the Microsoft Search blog describes how Bing adds value to the results of Major League Baseball related searches. Search for your favorite team and you will see the latest win/loss results, a schedule for upcoming games, and a one line summary of standings. Bing also provides real-time results for current games. Search for your favorite player and you will see a picture along with a table of their stats for the most recent game and a one line summary of their stats for the season.
In comparison, when you search your team in Google, you will see an inning scorecard of the most recent game. Also Google currently has nothing comparable to the MLB player results offered by Bing.
