Serena Williams passed her toughest test in career so far at the US Open to beat Karolina Pliskova and reach the semi-finals for a ninth consecutive time.
Williams who was seeded 17th, trailed 4-2 in the first set but fought back to win 6-4 6-3 against the Czech eighth seed.
The 36-year-old American is looking forward to grab her first Grand Slam trophy since giving birth to daughter Olympia last September.
If Williams emerge victorious at the US Open 2018, it would take her to a record 24th major title, equalling Australian Margaret Court’s all-time record.
Williams who spoke about her future was quoted by BBC Sport to say: “I don’t think I have another 10 years of having opportunities to be able to play and win championships,” said former world number one Williams.
“Every match really means a lot to me. I kind of go out there and I just do the best that I can.”
Williams will on Thursday face Latvia’s 19th seed Anastasija Sevastova in the last four, who edged out American defending champion Sloane Stephens earlier on Tuesday.
