Lydia Ko was once the dominant player on the LPGA Tour.
That was then, this is now and she had fallen from No. 1 all the way to 55 in the world rankings.
She looks to be finding that championship form again, the form that won her 15 LPGA titles, including a pair of majors. Lydia started Friday at the Marathon Classic with four birdies then finished birdie-birdie to shoot 65 and claim the halfway lead at the tournament she has won twice.
Ko is at 13-under, a shot in front of Jodi Ewart Shadoff (67-63) and two better than last week’s winner, Danielle Kang (65-67).
Those three are the only players in double-digits under par at Highland Meadows.
Ko won this event in 2014 then again in 2016.
