Badosa: "He's a champion".

If Paula Badosa is back to her best tennis, as evidenced by her title in Washington or her semi-final in Cincinatti, her partner, Stefanos Tsitsipas, is sinking.

Deeply lacking in confidence, the Greek disappointed once again, losing in the first round of the US Open to Thanasi Kokkinakis (7-6, 4-6, 6-3, 7-5).

Having qualified for the third round, Badosa expressed her support and confidence in the world number 11: "I hope we play tomorrow. We're looking forward to it. It's really nice to share the court together.

We spend time together off the court, but also on the court. It's really special at a Grand Slam tournament.

It's like a dream come true. My hat's off to him.

He's going through some tough times. But he's a champion and always will be."
