Japan's Naomi Osaka stunned world number 1 Simona Halep of Romania in the semi-final at the Indian Wells Masters here. The 20-year-old world number 44 made light work of Halep, beating her in straight sets 6-3, 6-0 in just 64 minutes of play on Friday night, reports Efe. The huge upset means Osaka moves on to the final on Sunday, where she will face another 20-year-old, Russian Daria Kasatkina, who beat Venus Williams in a nearly three-hour epic earlier on Friday.
