Serena Williams' win set up the 30th tour-level meeting between the Williams sisters. It is their earliest meeting at a major since the 2nd round at the 1998 Australian Open, the 1st professional meeting between the two sisters. Serena leads head-to-head, 17-12. https://t.co/fJ5MbkDT9Z
Serena has had a comfortable tournament so far. She despatched Poland's Magda Linette with little fuss in the first round. The six-time champion beat Carina Witthoft by straight sets in the second round.
Venus has found it tougher going than her younger sister. The 16th seed was taken to three sets in her opener by Svetlana Kuznetsova. She followed that up with a win over Italy's Camila Giorgi.
Guardian journalist Bryan Armen Graham highlighted the effect of the Williams' sisters meeting on tournament tickets:
While Serena has the better record of the two players, she will be well aware that Venus has won their only meeting of 2018 so far. The 38-year-old claimed a 6-3, 6-4 victory in the third round at Indian Wells. The match was the first time Venus had beaten her sister in straight sets since the 2008 Wimbledon final.
Friday's second match on Arthur Ashe also promises much excitement as Del Potro faces Verdasco. The powerful Argentine is in search of his second U.S. Open title and has been in good form in New York with comfortable wins over Donald Young and Denis Kudla.
The 29-year-old has explained why he is expecting a tough test on Friday night from the Spaniard, per ATP World Tour.
"Fernando is a really good player," he said. "I don't like to play against a lefty because they can mix it up all the time. They play different angles of the game. They make variations all the time. It's not going to be easy for me."
Del Potro will be expected to get past Verdasco despite his impressive win over Murray. The Argentine is a powerful opponent with a ferocious forehand and has shown signs of being back to his very best in 2018.
