The tennis gods work in mysterious ways, but they’re going to have a hard time explaining this one. We know they have an aversion to Roger Federer and Rafael Nadal playing at the U.S. Open—that much, after a decade and a half of their rivalry, seems clear enough. But deploying Grigor Dimitrov—loser of seven of eight matches entering the U.S. Open, a man whose ranking has dropped to No. 78 from a career-best No. 3 in November 2017 and had never beaten Federer—to work their divine intervention? Sure, after Novak Djokovic lost in the fourth round, it was obvious they’d have to get creative to prevent New York from at last getting its long-overdue Federer–Nadal showdown.
