Elsewhere Stefanos Tsitsipas takes ninth spot from American John Isner following the Greek’s victory at the Estoril Open.

Novak Djokovic remains first ahead of Rafael Nadal to mark the Serb’s 250th week as world number one, a record only bettered on four occasions in the past.

Japan’s Naomi Osaka remained atop of WTA rankings released Monday, ahead of Czech Petra Kvitova and Romanian Simona Halep.

The largely unchanged top 20 saw Belgian Elise Mertens drop two places to 20th after being knocked out of the first round of the Madrid Open on Sunday by Slovakia’s Anna Karolina Schmiedlova, 103rd in the world.
