No. 1? Lydia Ko On Verge Of Making History

While Tiger's blaming habits ingrained into his wedge game by Sean Foley and even knocking the bounce on his wedges, 17-year-old Lydia Ko is playing her first tournament without glasses but with contact lenses and despite the huge change, hasn't missed a beat.

Heading into Saturday's final round of the inaugural Coates Golf Championship (scheduled to avoid Super Bowl Sunday), Ko leads a stacked field.

And according to Randall Mell, some history is on the line when Golf Channel's coverage starts at 3 p.m. ET.

If Ko wins Saturday, she’ll vault to the top of the Rolex Women’s World Rankings, becoming the youngest No. 1 in the history of men’s or women’s professional golf. Ko can also take the No. 1 ranking with a solo second-place finish, as long as current No. 1 Inbee Park finishes in a three-way tie for third or worse.
