Naomi Osaka didn’t need to take her game out of cruise control on Thursday afternoon.

The two-time U.S. Open champion, seeded No. 23 at this year’s tournament, dominated American Hailey Baptiste, 6-3, 6-1, in front of a sleepy early afternoon crowd at Louis Armstrong Stadium.

The second-round match lasted just 70 minutes and ended with Baptiste, 23, serving up her 9th double fault on match point.
