Angelique Kerber won't celebrate her return to world number one with an Indian Wells title after a shock fourth-round exit Tuesday at the hands of Elena Vesnina.

Russia's 14th-seeded Vesnina toppled the second-seeded German 6-3, 6-3 to book a quarter-final meeting with seven-time Grand Slam champion Venus Williams.

Kerber, the 2016 Australian Open and US Open champion, is still assured of returning to number one in the world next Monday thanks to Serena Williams's injury withdrawal from Indian Wells.

Seven-time Grand Slam champion Venus Williams roared back for a 3-6, 6-1, 6-3 victory over China's Peng Shuai to reach the quarter-finals at Indian Wells. Williams was runner up to her sister Serena at the Australian Open in January.
