New court 'like a garden'

Garbine Muguruza won the first-ever French Open match to be played on the picturesque Court Simonne Mathieu, beating Taylor Townsend in three sets. The 2016 champion was impressed by what she saw.

"It's in a very different place. You don't feel like you are around court. It's like in a garden. It's a different feeling," she said.

From hero to zero

Italian Marco Cecchinato made waves last year in Paris with a shock victory over Novak Djokovic helping him reach the semi-finals as the world number 72. Twelve months on, though, and seeded 16th, he blew a two-set lead to lose 2-6, 6-7 (6/8), 6-4, 6-2, 6-4 against French veteran Nicolas Mahut.
