Jannik Sinner to play Alcaraz in China Open final, Pegula crashes out

The 23-year-old Italian is the defending champion and hasn't appeared distracted by the World Anti-Doping Agency announcing Saturday it was seeking a ban of one to two years for the U.S. Open champion, who tested positive twice for an anabolic steroid in March.

Chinese wild card Yunchaokete, ranked 96th, held his own in the heavy baseline exchanges to put pressure on Sinner's service games, but couldn't take any of his three break-point chances in the first set.

Sinner's experience proved crucial during the pivotal moments, especially in the second-set tiebreaker, where he surged to a 6-1 lead.
