How’d they do it? Bloomberg Businessweek posted a lengthy story last week on how Sergio Tacchini, the Italian brand that is now controlled by Chinese investors, saved itself — from itself. Their biggest move? Nabbing Novak Djokovic, of course. But our favorite part of the feature was this snippet on player-turned-fashionista Martina Hingis, who had a sour relationship with the company:

Hingis dominated the women’s tour during the second half of the ’90s. She seemed to fit well into the Tacchini firmament, appealing to wealthy, casually athletic, European-oriented fans. It didn’t work out. Three years into Hingis’s five-year deal, worth $5.6 million, Tacchini fired her, accusing Hingis of not wearing the clothes as contracted. Two years later, Hingis sued, claiming that the “defective” Tacchini shoes she wore had wrecked her feet and ruined her career. (Hingis had surgery in 2001 and 2002 to repair ligaments in her ankles.) A New York court dismissed the suit, ruling that the case should be heard in Milan, where Hingis had signed the contract and where another suit was pending. In 2006 her manager, Mario Widmer, told a German newspaper that “the Tacchini problem is resolved. We have come to a compromise and at the same time have agreed to keep silence on both sides.”

More from those financial folk: While Businessweek was focused on Sergio, The Economist‘s new “Game Theory” blog is paying plenty of attention to tennis. Who now? Andy Murray.
