Overview

• Novak Djokovic beat Zizou Bergs 6-3, 7-5 to reach his 80th Masters 1000 semi-final and became the oldest semi-finalist at this level at 38.
• He will face world No. 204 Valentin Vacherot, a Monaco qualifier who upset No. 10 seed Holger Rune 2-6, 7-6 (4), 6-4 and is set to break into the top 100.
• Djokovic has struggled with the heat and humidity all week, vomiting in an earlier match and requiring treatment against Jaume Munar, saying he was "just trying to stay alive" on court.
• The four-time Shanghai champion is two wins from a record-extending fifth title in Shanghai and a 41st Masters 1000 crown.
