A Monday afternoon men’s final at the U.S. Open is unusual enough – but the players vying for the title this year are even more so. It’s the first time in a long time, almost a decade, that the final is being played by someone outside of the men’s game’s so-called “Big Four” – Novak Djokovic, Roger Federer, Rafael Nadal, Andy Murray. It’s the first time that the U.S. Open men’s final will be played by two double-digit seeds: No. 10 Kei Nishikori of Japan (pictured) and No. 14 Marin Cilic of Croatia – and it’s the first time ever for an Asian male player to reach a Grand Slam final.
