LOS ANGELES – Russia’s Maria Sharapova returned to Indian Wells after three years, only to lose in the first round to Japan’s Naomi Osaka 6-4, 6-4 on Wednesday.
Osaka will now play Agnieszka Radwanska, ranked 31st, in the next round.
Meanwhile, Sam Stosur recovered after losing the first set to American Lauren Davis to win the game 3-6, 6-3, 6-3 and advance to the second round, where she will face Kristina Mladenovic.
Sixteen-year-old Amanda Anisimova beat 94th-ranked Pauline Parmentier 6-2, 6-2 to set up a second-round clash against Anastasia Pavlyuchenkova.
“I’m really proud of myself. The biggest thing (in the pros) is about being tougher mentally. I try to take things one point at a time,” Anisimova told the Tennis Channel.
