Germany's Philipp Kohlschreiber stunned Australian Open champion Novak Djokovic 6-4, 6-4 on Tuesday, claiming his first career win over a world No. 1 player to reach the fourth round of the ATP Indian Wells Masters. "I need to do what I want, and what I want is to play the tournaments I want to play".
"You just have to deal with it, move on, turn the next page", Djokovic said.
Kohlschreiber notched his first ever victory over a number one-ranked player, ending Djokovic's bid for a sixth Indian Wells crown.
But in a match that resumed after rain stopped play following completion of just one game on Monday night, Kohlschreiber looked crisp and confident, breaking the Serbian star for a 4-3 lead in the first and pocketing the set with a service victor on his second set point.
"I haven't played that much, so I wanted to make it count", said Williams, who is ranked No. 36 and expects to play about 12 tournaments this year. I was focusing on my game. "So these are the rare occasions where I could potentially do well", Djokovic said.
Bencic - who beat four top-10 players on the way to the title in Dubai last month, her first trophy in four years - next faces fifth-seeded Czech Karolina Pliskova, who downed Anett Kontaveit 7-6 (10/8), 4-6, 6-2.
"Today, with Novak being number one, top-seeded here, it's a very incredible win for me". I had two good wins. I'm hitting the ball well. I'm really happy with myself. "So just things worked out for me". "But it's everything I could do today".
Djokovic was the biggest casualty of the men's draw.
Spain's Muguruza, a two-time Grand Slam champion now ranked 20th in the world, out-lasted seventh-ranked Kiki Bertens 5-7, 6-1, 6-4 while Williams, a seven-time Grand Slam victor, beat Germany's Mona Barthel 6-4, 6-4.
Bianca Andreescu, an 18-year-old Canadian, beat 18th-seeded Wang Qiang 7-5, 6-2. Her triumph in Australia made her No. 1 for the first time, but her time at the top has been rocky.
