The return of Sergio Tacchini
World #1 Novak Djokovic defeated World #42 Gilles Muller of Luxembourg in straights, 6-4, 7-5, 7-5 in the 4th Round of the Australian Open. That result's notable from a tenniswear standpoint- Djokovic left Sergio Tacchini for his own Uniqlo line after the company couldn't keep up with the endorsement payments, and Muller wears the ST brand now. This look below is definitely reminiscent of John McEnroe back in the day.
A check of the ST website shows 11 pros now wearing the line. If you poke around the website, check out the shoe section. This first shoe is called the Roma LT, which looks like a performance tennis shoe:
And this model is the Gran Torino, which looks like a casual model.
