Jason Day and Lydia Ko carded the low round of the day in foursomes format, a 66, to move into the lead at 20-under at the Grant Thornton Invitational.
“I think this is just a great experience for me and I hope a lot of juniors who are either here this week or watching on the TV get inspired and hope that one day they play on the PGA or the LPGA and they too are paired up with another fellow player on the other tour," said Ko. "This is I think the outcome and result is secondary. I think for us, we don't really get to I guess cross paths that much with other tours. Jason's only the fourth PGA TOUR player I've played with. I think it's a great -- something that I can learn a lot from.”
Overnight leaders Tony Finau and Nelly Korda shot a 70 to move down into a share of second place at 18-under.
Lucas Glover and Leona Maguire closed with a 69 for their share of second place.
The Grant Thornton Invitational is a first-year PGA TOUR Challenge Season event (unofficial) and the first mixed-team co-sanctioned event between the PGA TOUR and LPGA Tour since John Daly and Laura Davies won the final JCPenney Classic in 1999.
