Leona Maguire and Lucas Glover remain tied-second at the Grant Thornton Invitational, two shots adrift of the leaders heading into the final round in Florida.

Maguire and Glover - the 2009 US Open champion - posted a three-under par 69 in Saturday's foursomes play, to climb to 18-under par for the tournament.

They lie two strokes adrift of leading duo, Jason Day and Lydia Ko, whose 66 lifted them onto 20-under heading into Sunday.

FULL LEADERBOARD

Overnight leaders following Friday's scramble, Nelly Korda and Tony Finau, join Maguire/Glover on 18-under, after a second round 70.

The tournament features 16 mixed teams of one male and one female player.

The teams played a scramble format on Friday, foursomes (alternate shot) on Saturday, while Sunday will be a modified four-ball, where both team-mates will tee off, then switch balls for their second shots and play that ball until holed.

Four pairings lie in tied-fourth on 16-under - Brooke Henderson and Corey Conners, Lexi Thompson and Denny McCarthy, Megan Khang and Nick Taylor, Ruoning Yin and Rickie Fowler.
