TENNIS NEWS - World number one Garbine Muguruza retired feeling unwell at the China Open as US Open winner Sloane Stephens was again defeated in the first round.
Spaniard Muguruza, 23, lost the first set 6-1 to unseeded Barbora Strycova, 31, from the Czech Republic.
Wimbledon champion Muguruza then called a medical timeout at 2-0 down in the second set and retired after having her pulse taken courtside in Beijing.
"It's very tough, I got a virus in Wuhan," said the 2015 Beijing champion.
"I couldn't perform today. It's the easy way to think 'don't go on the court'. I want to feel like giving the last chance, going on the court, just hit a few balls, see how I'm going to feel, try to turn things around.
"I don't want to retire before the tournament starts."
