Ochoa finished at 18-under 270 on The Senator course at the Robert Trent Jones Golf Trail's Capitol Hill complex to snap an 11-start winless streak dating to the Corona Championship in late April. The top-ranked Mexican star has three victories this year and 27 overall on the LPGA Tour.
"There are places where you feel comfortable and you feel a good vibe and you like the course," Ochoa said. "This has been really good for me. I feel comfortable here. I have a lot of good memories."
