Does Zverev's top-ten record fit a world number one?

In Paris, Lorenzo Musetti beat Alexander Zverev in straight sets on Wednesday, and Zverev said he played really badly. The New York Times reports it was Zverev's first match as world number one, the thirtieth man to reach that spot since computerized rankings began.

The New York Times says Zverev has won 2 Grand Slam titles this year, more than any other men's player. The top-ten record is the harder test.

Against top-ten players, the New York Times counts 12 matches, with 3 won and 9 lost. Set against two majors, that record is the question his top spot has to answer.
