Serena Williams stayed on course to win her sixth Wimbledon title by beating her sister Venus in the fourth round.
Serena Williams marched into the quarter-finals of Wimbledon by outclassing her sister Venus on Centre Court.
Top seed Serena said she was "in awe" of the way her elder sibling had been playing ahead of their fourth-round meeting on Monday, but never looked like having her hopes of winning all four grand slams this year ended by Venus.
World number one Serena won 6-4 6-3 and will take some stopping as she goes in search of her sixth title at SW19.
The irrepressible Serena had won 14 of her previous 25 matches against Venus and improved that record in style despite the 35-year-old's impressive form this year.
Venus and Serena embraced over the net after the tournament favourite came up with 36 winners and broke four times to move into the last eight.
Serena overcame a major scare to beat Heather Watson in the third round last Friday, but looked in no mood to be pushed all the way by her sister as she won the first eight points of the match to lead 2-0 after only three minutes.
Venus got on the board to make it 2-1 and drew level when her younger sibling netted, but she failed to take the initiative and a couple of errors followed by a stray backhand ensured Serena claimed the upper hand once again.
Serena was not having things all her own way, but wrapped up the first set in emphatic fashion by coming up with three booming aces.
The impressive Serena earned another two break points at the start of set two with a sublime forehand winner, but veteran Venus - who had the majority of the crowd on her side - refused to lie down and showed great character to hold.
Serena was not allowing Venus such opportunities on her serve, but the elder sister was hanging in there as she saved another break point in her next service game.
A further two break points were saved by Venus in the seventh game of the second set, but a double fault gifted a break to Serena.
Serena held again with minimal fuss and sealed the victory with another break, earning three match points and winning the first when Venus sent a shot long to end the contest in only an hour and eight minutes.
