Katie Boulter said she was happy to put "a tough couple of months" behind her by beating Hailey Baptiste in the China Open. The British number two defeated the American 7-5 5-7 6-4 to progress to the second round in Beijing. The 29-year-old was knocked out of the second round of Wimbledon by lucky loser Solana Sierra then lost in the first round of the US Open to Ukrainian Marta Kostyuk. "I've had a tough couple of months," Boulter said. "She [Baptiste] was playing such disruptive tennis but I stayed mentally strong and found a way to get through it.
