Seven times Wimbledon champion Roger Federer booked his passage to the quarter finals with a straight sets victory over veteran Spaniard Tommy Robredo.
Federer has lost to Robredo only once in 11 previous meetings, at last year's US Open, and today on Court One and on his preferred grass he was invincible.
Federer is likely to face fellow Swiss Stan Wawrinka who was two sets to love up against another Spanish veteran Feliciano Lopez.
Federer's 6-1, 6-4, 6-4 victory was achieved in little more than an hour and a half.
He is bidding for a record eighth Wimbledon singles title and 18th Grand Slam to equal Chris Evert and Martina Navratilova who are in joint fourth place on the all- time list.
Meanwhile On Centre Court. There was a titanic struggle between two great base liners Maria Sharapova and Angelique Kerber.
Kerber, the German ninth seed, earned an early lead when she won the first set tiebreak 7-4.
But Sharapova fought back characteristically to land the second set 6-4 with the volume of her screams almost matched by Kerber's.
In the final set Kerber broke the Russian's serve in the second gameand as the level of play rose, the rallies became longer and longer.
Kerber scrambled and scrambled to maintain her advantage before an enraptured crowd which included the champion of yester year Maria Bueno from Rio de Janeiro.
Prior to today, Sharapova held a 4-1 win record over Kerber but the latter likes grass and greater consistency showed. Nevertheless Sharapova had to save a match point on her serve at 2-5.
At 5-3 up Kerber's nerves began to show. She served a double fault at 15-15 and lost the game to be clawed back to 5-4.
Then it was Sharapova's turn to falter as she went 0-40 down. She battled back to get to deuce before a forehand error produced another match point.
On the sixth match point, Sharapova produced another astonishing forehand winner but she overhit another forehand on the seventh of a truly thrilling encounter which gave Kerber victory 7-6, 4-6, 6-4.
