Primetime Semifinals In New York

Welcome back to the WTA Insider Live Blog, taking you inside all the action at the 2016 US Open. It's semifinals day in Flushing, headlined by World No.1 Serena Williams taking on No.10 seed and Western & Southern Open winner Karolina Pliskova. Pliskova knocked out No.6 seed and Serena's sister Venus en route to her first Grand Slam semifinal; the Czech will not only try to reach her first Grand Slam final, but also become just the eighth woman to defeat both Williams sisters in the same tournament. Later on, No.2 seed Angelique Kerber takes on two-time US Open finalist and former No.1 Caroline Wozniacki. It's a full circle moment for the German, who finds herself in the semifinals of the US Open for the first time since her breakout fortnight in 2011. Who has the edge under the lights?
