Don't quit your day jobs, professional tennis players.

Some of the top ATP and WTA starts were asked to spell “Cincinnati”—the host city of this week's Western & Southern Open—and for many of them, it did not go according to plan.

Ons Jabeur went with “Sini…I missed something,” while Grigor Dimitrov wasn’t even close, going with “Ciniti.”

There were some other letter-based gaffes, though J.J. Wolf breezed through the challenge, while Matteo Berrettini sweated it out.

The Western & Southern Open came to a close with a men's final befitting the alphabet, with Andrey Rublev facing Alexander Zverev.
