Tuesday Recap

Federer and Nadal came through their opening encounters at this year's Wimbledon.

It initially appeared Federer could be in for a difficult match against Harris, with the South African's serve accurate and true. The 22-year-old claimed the opener 6-3, surprising fans on Centre Court.

However, the Swiss turned on the style from that moment, and he dominated the last three sets to overpower his opponent.

Federer served nine aces on his way to the victory and won 94 per cent of his points at the net.

Nadal was too good for Sugita and never appeared under pressure against the Japanese player.

The Spaniard broke Sugita's serve at will, crushing his opponent's confidence at every turn.

Nadal only conceded two double faults in the match whilst hitting 26 winners, and the icon calmly made his way into the next round.

Williams displayed magical moments in the opening set of her contest with Gatto-Monticone but had to battle in the second to complete the victory.

The American legend broke the Italian's serve three times to claim the first, but Gatto-Monticone improved before exiting the competition.

Barty's campaign to win her second Grand Slam began in style with a simple win over Zheng.

The confident Australian is fresh from her success at the French Open and will be a serious threat at the grass-court championship.

Kerber also appeared in excellent shape as she began the defence of her Wimbledon crown.
