SHANGHAI: Fourth seed Novak Djokovic battled past a spirited Zizou Bergs 6-3, 7-5 on Thursday to reach the Shanghai Masters semifinals for a 10th time, setting up a clash with surprise package and world No. 204 Valentin Vacherot. In challenging conditions, Djokovic was made to work harder than the scoreline suggests by his Belgian opponent, who actually registered more winners than the four-time champion but was undone by unforced errors. “First encounter with Bergs, a great guy. Obviously a lot of firepower in his game. He played a good game,” Djokovic said.
