Former world number one Roger Federer has returned to third in the ATP Men’s rankings released today, replacing Alexander Zverev after the reigning champion was knocked out of the Munich Open at the quarter-finals stage.

Federer, who has won a record 20 Grand Slams, is making his return to clay at the Madrid Open this week after three years’ absence.

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 Women’s rankings, 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.
