Aditi had a steady start and a steady finish but in the intervening holes she saw a lot of action with four birdies and two bogeys and just one par between 7th and 13th holes on the opening day.
Aditi, who has a steady rookie season, parred the first six holes and she also parred the last five holes. But in between she birdied the seventh, ninth, 11th and 13th holes and dropped a shot each on eighth and 10th.
The opening day belonged to Lexi Thompson who was off to a fast start. Thompson racked up 11 birdies against two bogeys at Brickyard Crossing Golf Course, the Pete Dye-designed track that partially lies within the 2.5-mile oval racing surface.
She carded 9-under 63 and one shot behind Thompson are Sandra Gal of Germany and Kris Tamulis, who had bogey-free rounds. Two shots off the lead are Moriya Jutanugarn of Thailand and Lydia Ko of New Zealand.
