Tony La Russa is suing the social-networking site Twitter, claiming an unauthorized page using his name damaged his reputation and caused emotional distress. The suit filed last month in the Superior Court of California in San Francisco seeks unspecified damages. Messages left Thursday with La Russa's attorney and San Francisco-based Twitter were not returned. The lawsuit claims that someone created a false account under La Russa's name and posted updates, known as "tweets," that gave the false impression that the comments came from La Russa. The suit said the comments were "derogatory and demeaning" and damaged La Russa's trademark rights.
