So, the big question: Is Rafael Nadal firing on all cylinders in his quest for a 10th French Open title?
Short answer: It is still too early to tell, because through the first three rounds, he has yet to be seriously tested.
Andrey Kuznetsov certainly wasn't a reliable gauge of the 14-time Grand Slam champion's form in a clay-court season when his ranking has slipped to seventh — the Spaniard's lowest spot in a decade — and which Nadal himself acknowledges has been "up and down."
Kuznetsov, ranked 120th, folded 6-1, 6-3, 6-2 in their third-round match Saturday.
