Federer back to third after Zverev's Munich knockout

Paris: Former world number one Roger Federer has returned to third in the ATP rankings released Monday, 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.

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.
