Carlos Alcaraz and top-ranked Jannik Sinner showed no signs of fatigue from their China Open final earlier this week to advance with comfortable straight-set victories in their opening matches of the Shanghai Masters on Saturday. The second-ranked Alcaraz, who beat the Italian in Beijing on Wednesday for his fourth title of the year, recorded his 10th consecutive win with a 6-2, 6-2 result against 19-year-old Shang Juncheng of China. “I’m not used to playing against players younger than me,” Alcaraz said.
